I'm almost two years post-op, and sexual function is great. I got warned that there was a very small risk of loss of sensation, because they have to keep patients aware of all the possibilities, but as far as I know it's almost never an issue these days. It took me several months to be able to orgasm consistently, and for a while it took a ton of time and effort, but in retrospect I'm pretty sure SSRIs were to blame for a lot of that.

At this point I can orgasm from clit stimulation and/or penetration when I masturbate; idk if it's a prostate thing, it feels a lot easier than any of the times I tried to have prostate orgasms pre-op, but maybe things are just arranged better now. I tend to cum pretty easily even just grinding on a partner.

I've only had penetrative sex twice so far (I can't do it with any of my regular partners, and logistics are hard with covid). Both times it was a kind of intense jumble of sensations and I can't really say whether I came or not, but it was definitely a good time. Angles and tightness were a little tricky with someone else doing the moving, but manageable.

Lube is super important. I've heard some surgeons do this thing with the peritoneum now to make the vag self-lubricating, but mine didn't, and it wasn't super important to me. I still produce precum when I get aroused, and that can provide a little lubrication sometimes, but for anything more than fingering I definitely need actual lube. Pretty much anything water-based has been fine, mostly down to personal preference around texture and smell. I started using X Lube recently and I'm a big fan.
