A lot of my fantasies are rehashed variants of memories of sexual encounters of my past. One recurrent fantasy is of guys who were dear friends of mine back in the day; wishing they weren't quite so Straight.
If you don't ask you will never know. And if they are a good friend they can always say no. But there again they might just say yes. Who knows unless you ask
There are a couple porn videos I watch frequently that are basically the same as your doctor fantasy. But they all revolve around a girl having habitual wet dreams and the doctor helping them squirt.
A lot of stuff with friends and neighbors. One I've been using as of late is me and a neighbor are doing laundry together in our building's laundry room. She sees I'm washing women's underwear and says something about it's nice that I do my girlfriend's laundry. I explain that I'm feminine genderqueer and it's my underwear. We compare some of our favorite pairs and then go upstairs to one of our apartments and try on each other's underwear and comment on which ones we like best on the other person before taking a shower together and then masturbate together.
Last time I was thinking of some fun things with my high school girlfriend....you know how your mind embellishes and builds on what really happened but that's still burned permanently into my brain. I kind of went through the sex sequence of our relationship and tried to think of as many of the 'events' as I could....I don't think I have forgotten much....of course, I bet she is like - who was that ? Fun nonetheless.
Most of my fantasies for the last 33 years have been about other guys, many different same-sex activities. At this point I've done a lot of things with guys. The one big thing I haven't done is bareback fucking, so this is by far my greatest fantasy these days. I have fucked guys, as a top, with condoms, but nothing bareback. How wonderful it would be to get together with a special guy, get naked, rub our hands all over each other, kiss each other all over our bodies, sucking and deepthroating each other's cocks, and finally settling into a long, passionate 69. Finally, with my cock deep down his throat, I pull my mouth off his cock, and stretch my neck to lick the puckered opening of his asshole, just under his balls. It's a stretch, but I sink right in, pulling his ass cheeks apart with my hands, my entire face deep into his crevice, my tongue inside of his hole. We continue in this way, at one end my cock fucking his throat, and the other end my tongue fucking his asshole opening. I begin to work my saliva drenched fingers into his opening, playing with his hole, pushing inside of him. I feel him reacting with intense pleasure. Finally we roll up and off each other, and I pull him with his ass towards me, my face once again diving between his cheeks, my tongue finding his delicious hole. I lick it with hunger like you've never seen before. I then pull up and place the head of my bare cock against his tight puckered opening, rubbing it all around, enjoying that feeling of my bare cockhead rubbing around and around his bare asshole opening, with that inevitable uncontrollable need to push inside of him. And then I begin to slip it inside, through and past his outer sphincter, and then past his inner sphincter, and then deeper and deeper inside of him until my entire cock is buried in his anal canal, bare skin on skin. Finally I have my natural cock deep inside another man's beautiful gay asshole, feeling the sensation of the skin of my cockhead rubbing against the velvety walls of the deep inner recesses of his manhole. And I slowly begin to fuck him, pulling my cock out almost all the way, feeling that sensation along the skin of my shaft against the walls of his asshole sphincters as it slides past, and then back down again, deep into him. Up and down, in and out, fucking him faster and faster. I grab onto his hips with a firm hold to pound his ass. Minutes go by, or is it hours? I pull out, and forcibly flipped him over onto his back, pushing his legs apart, pushing his knees to his chest, as I grab a tube of lube and squirted it all over my cock, and push myself deep inside of him again, making love to his hole with a passion like this world has never seen. I love watching the ecstasy on his face, and his rockhard cock pulsing under me, standing straight up from his body in some weird way. We fuck like animals, or perhaps more aptly, like real man. I've never felt closer to a human being ever in my life than what I feel now in this moment, joined together with his man in this raw manner, the way nature always intended. I am pounding away at his hole, holding myself up with my strained arms, sweat pouring from me, from both of us, my mouth open and gasping for breath, my body above him, my face above him, when all of a sudden I feel and taste semen inside my mouth, and then see a steady stream of cum blasting out of his cockhead, and into my gaping mouth. And I quickly close my lips to savour and swallow, before opening for the next volley. But it misses me and covers my face. Two more shots shoot out, again covering my face, despite my open mouth trying to receive that man nectar. And then I feel it, from deep within, deep inside of me, from a place of power like I've never felt, an orgasm building, and finally exploding upwards. I quickly jam my cock as deep into him as I can, perhaps even the tip of my cockhead slamming against that deepest of sphincters that lead into his colon. And then I release. It's an orgasmic release like I've never felt before, exploding from not only deep within me, but from every cell of my body, feeling like it's everything I have coming out of me and into him. And I know my cum is filling his anal cavity all around my cock inside of him, filling every cubic millimeter. My cum seed essence is filling him. I've never had a child of my own, but right now, in this moment, I just know that my seed has always been meant for this man and other men. I was born to share my sperm with guys, and guys alone. I've never fucked a woman without a condom, and no men either, not until this moment, until this glorious moment that he and I are sharing together. So who else have I saved my sperm for than this man, and many future men. My very essence, what makes me me, to be shared with men. Besides this--what feels like a neverending physical orgasm--my mind is having an orgasm of its own, thinking of how I am sharing my gay DNA with another man, that will merge with his body and become one with it. Someday soon I know another man will do the same for me, share his gay DNA with me, to become one with me through my asshole. I didn't notice that I have fallen down on top of him, my arms tightly embracing his body, his legs and arms tightly wrapped around my body, myself still in the throes of my orgasm, and my male gay lover in the afterglow of his own, and with both of us locked in a deeply passionate kiss. I've never known such bliss. This is heaven on earth. And now that I've gone onto PrEP, I know that this fantasy, like all my others, will come true very soon. I fantasized 33 years ago of seeing another man's cock up close, and it happened. I fantasized about stroking another guy's cock and sucking his cock, and a while later it happened, and then hundreds of times. I fantasized about 69ing with a guy, and it happened. I fantasized about kissing, licking and tonguefucking a guy's asshole opening, and it happened. I fantasized about inserting my cock into another man's asshole and fucking him, and it happened. I fantasized about having a threesome with two other guys, then having group sex in a small group, and then being part of a large gay orgy, and all of them came true. I fantasized about making out with a guy, passionately kissing, and it happened. I fantasized about going out on dates with a guy, and it happened. I fantasized about developing romantic feelings for another man, and it happened (twice, so far, though both unrequited). So without a doubt my bare cock is going to become one with another man's asshole, and very soon. And I've got a number of fantasies that will come after that. For a man swimming in gay desire, they are endless.
I get into fantasy stuff with a wild mix of anime and twisted storylines, especially the ones with dark plots and power shifts. I usually scroll through https://hentaiz-a1.net for whatever hits the spot, there’s a lot there and some pretty intense scenarios that really spark the imagination. Sometimes the most random tags lead to exactly what I didn’t know I was looking for.
I usually fantasize about stuff I have done in the past, my favourite two are an ex gf who had a pee while she was giving me a blowjob outside and another old gf who dressed up in a wonder woman outfit and rode me to drain every last drop of cum from me
Pretty much all my fantasies are some version of that: Me and a non-romantic partner are hanging out and something we're doing eventually leads to us masturbating together. I don't fantasize about having sex very much. The only ones that involve sex are imagining friends or an ex and some random hookup having sex in front of me. Like someone else above said, for ones where I'm having sex with somebody, I use actual memories.
