Many married guys that have been separated/divorced took the opportunity to explore sex whenever possible which might have led to more than you ever expected. Women who wanted threesomes, which led to your first cocksucking experience. I was stupid and didn't read the signs, since nobody mentioned double teaming this barmaid, I left them and went home, I wasn't going to be the one to mention it. My second opportunity didn't get away from me. It was not only for the experience, it was the need. It woke up a different side of things for me. Do you have something that directed you to doing it , and you kept at it?
When I look back there are times I think a female friends or acquaintances might have been happy to hook up for NSA sex, being married I'm cautious but also didn't read the signs. I'd be down for most things given the chance but still married so not confident in making the first move.
For me, when I was with my last girlfriend for three years that ended just before the pandemic hit, I had powerful gay feelings throughout the very rocky relationship. But other than reading and writing in forums like this, and looking at and posting gay porn, I never cheated on her. I just couldn't hurt her that way, even though she knew everything about my gay side and every detail, in general, of my past activities with guys. But I just couldn't continue living the lie and denying my needs, so I broke up with her. Of course that's nothing like a long marriage. But it was something that I had to do, and the other difficulties in a relationship also helped me do it. But, OMG, as soon as we were apart, the gay floodgates just opened in me, and I was so determined to explore my gay side in every way. The feeling of freedom to be myself was so joyous. And then the pandemic hit! Arghgh! I've had some sex with guys over these almost 3 years, but it has been very eye-opening vis-à-vis this freedom. I had lots of gay sex, almost exclusively oral, before that relationship. But I've learned so much about myself and the gay side of myself in that relationship and since, and now that I'm starting PrEP in a couple of weeks, 2023 is going to be a very different year for me, and it will be very gay, at least sexually, and perhaps in more ways.
Every time I sucked a guys cock I did it for the experience. How his cock was going to feel in my mouth, how he was going to respond to my mouth sucking his cock, his moans when I rim his ass while stroking his cock, what he says when I deep throat his 9" cock while messaging his asshole, and then ultimately how vocal he will be when he cums in my mouth and I keep his entire cock deep in my throat as he holds the back of my head down and feel his warm load shooting down my throat, what he says when I continue to suck his cock clean, looking up and into his eyes. I love it as he collapses on the couch while I hold his balls and slowly continue to milk his cock of every tasteful drop of cum he got inside him. After he blows his load in my mouth is my favorite moment as I feel his hardness diminishing while still hold a grip on his member with my mouth and lips milking it from base to tip as I switch to sucking his shaved balls as I slide my tongue along his perineum and asshole to once again take his softening cock back into my mouth as it becomes spongier and stretchier with my firm oral grip. The best moment is taking his entire cock down and your nose meets his tummy, he cannot help but moan in pleasure as your throat grips his cock. If I'm lucky my continued oral work will bring his cock back into hardening to continue sucking him for another 40 mutes and get a second load of his cum. Not all guys can do so, but I've experienced many that could and was complimented immensely for having drained them as they rarely get drained. The guys I've sucked off in my lifetime know I can suck for hours on end, have done so and love doing so which is why they kept returning time and time again.
Being a cocksucker has been an evolution for me, to now truly being able to massage a guy's cockhead deep down my throat using my throat muscles, with my lips massaging the base of his shaft where it meets the pelvis. But you, @LowHangers, take it to a new level. You inspire me even more.
