I'm 64 and have been a dedicated barebacker for around 10 years. I was more verse until 6 years ago when radiation treatment for prostate cancer left me with "performance issues." Since I started as a devoted bottom boy, it was a return to my roots!
I've been HIV+ for close to 30 years, and only began barebacking when I had a hookup with a younger man (I would have been in my 50s at the time) who was about to penetrate and asked "Do you want the load?" I'd disclosed my HIV status and was a little surprised (this was pre-PreP) but answered "This is an option? Sure, go for it." It felt so much better without the rubber (turns out I had developed an allergic reaction to latex) that I never looked back and have pretty much looked for and found bareback partners for sex play since then.
Before the prostate cancer, I was actually topping more often, since going through the clean-out to bottom is sort of a drag. I had a few different guys I'd fuck regularly. I love different body types: one was a blonde twink runner (HIV+, 5'7", 115 lbs, lean, shaved body with a really sweet, tight hole); another a 30/40-ish muscle guy (on PreP, 5'10", 160 lbs, shaved with a soft, smooth hole, felt AMAZING to penetrate); another was a French guy living in NY (HIV+, 5'7", 130 lbs) lightly hairy, average body with a hot butt), and another muscled guy (on PreP, 5'10", 165 lbs, hairy, HOT butt). In addition there were a couple of one-offs, a hairy, stocky muscled Latin guy (HIV+, 5'9", 170(?) lbs) and an Asian guy with a smooth, athletic body and butt (on PreP, 5'7", 140 lbs).
They all took my poz loads up their butts completely willingly. FUCK! It felt so good to shoot bare inside a guy's hole after years of condom-only sex. Cumming is always good, but I'd say my best orgasms were with the the blonde twink runner and the shaved muscle guy and the one-off Asian guy. They were into my favorite foreplay, licking my ass - never fails to get me going. The others were good (dick sucking, kissing, etc.) but not as intense.
I would say, though, that the French guy was a lot of fun (I slipped off the condom and stealthed him BB first time, didn't cum inside him). He really loved getting fucked, sucked dick and licked balls, loved having his ass opened up with my mouth and then taking my cock. We'd fuck missionary position, and he'd stroke my balls while I fucked him (once with both hands) so that I'd explode inside him. Then I'd stay inside him and he'd beat off with my dick in his hole until he shot.
The runner boy would let me sit on his face and just go to town licking out my ass - I'd eat him, too. Or I'd stand and push my ass in his face (rimming obsession here, giving and receiving). His hole was tight, felt so good. The first time I came inside him was doggy-style; I thought we'd try a few different positions, but that sweet little runner's butt squeezed it out of me right away. The other times I remember best were once with him laying flat on his front, I held him in place with my hands under him right where his thighs met his pelvis (major explosion while his cum hole gripped my dick); and once he rode me reverse "cowgirl" and let his right hand trail up and down my balls to another surprise orgasm (so hot seeing his butt riding my cock and his fingers stroking my nut sack in time with his pole-riding).
The shaved muscle guy was totally sub/power bottom. He had the best DS: (dick sucking lips), made it feel like a cum hole: soft mouth without a hint of teeth. I'd fuck his face with him on his knees or back, then put my crack over his mouth and order him to eat my ass. I also had him sit on my face and delved into those muscled cheeks with my tongue, delicious butt. He really liked missionary/scissors position (right leg over my left shoulder, left leg straight) because he always wanted to play with my balls (a favorite thing for both of us). He'd stroke them while he sucked my dick and once I'd penetrated that AMAZING hole, would gently finger my balls while I pumped in and out of him. I'd always cum so hard inside his neg muscle butt...
The one time with the Asian boy was incredible. He was a power verse bottom and we got into a great 69 rimming each other's butts. He went into doggy style, and as soon as I'd penetrated his super-tight hole (surrounded by the prettiest ass cheeks) he was tickling my balls....5, 4, 3, 2, 1 BLAST OFF! Damn, I flooded his neg hole with my cum, such a turn-on!
Hope you enjoyed...here are some pics of the butts mentioned.
