As I have a sexless wife, and retired, I often get the urge to enjoy my cock. I have some condoms but usually I have a little sandwich bag or such, with a tissue in it. If I need to shoot out my load I shoot it into the little bag and tissue so I can just slip it into the bin. I used a condom when I have the opportunity for a long session, maybe sleeping on the couch. I slip it on my hard on and I can keep it stiff for quite a while. I can freely leak pre come and shoot my come-out without having to clean up the mess. The reduced sensation has me last a fair bit longer. In my younger single days I was free to launch it out and not worry about the mess. I loved watching the jet of come shoot out onto my stomach or into my hand.
Sometimes I would walk from the bedroom to the batroom when ready to cum and just shoot it into the toilet. Other times I would use our sex towel. Lately I just shot it on my belly and clean it up with toilet paper.
I have been the same since my horny 20's. I wanted a full load out of my cock straight into my mouth but the desire went. It was more of a fantasy desire when there was no other stimulus to pull myself to. I have managed to come in my hand and eat it all now and then but it wasn't the big loads I shot put in my 20's. Still I could get used to the taste. How bi guys take long jets of come into the back of their mouths I don't know. I never have tried licking it back out of my wife. That' s a real turnoff for her.
When I'm masturbating, part of the whole experience is having it hit my chest. From there I just take it away with whatever is around. When I'm masturbating outside I'm always standing and it feels different as I'm releasing in front of me but not feeling anything hitting my chest.
Your situation is very common. I started eating mine for the same reason. We get turned on with our wives eating their own pussy juice and we expect them to take our load so why not be man enough to do it as well? I saw a recent anonymous poll with married straight guys. Here are the results: Men, do you eat your own cum? No, but the idea excites me. (25%) Yes, but only solo so far. (23%) Yes, both from my wife and solo. (22%) No, and I never would. (17%) Yes, but only from my wife ("cream pie" after sex or "snowball" after a blowjob) (14%)
There are 3 places I put my cum into. My mouth directly, or into a glass so I can drink it during the next jerk off session, or into a pair of pantyhose. It is usually the first two. Nothing is more erotic than feeling cum splashing into my mouth, and it really amps up the pleasure of orgasm.
Not sure of your age, but I'm 72. I normally try to jerk off at least once a day, but it is dry. Now if I wait a few days, or maybe miss some prescriptions, I can still get a little.
