While I don't think this is the best place to ask, I agree with Felix in that I have one and I can try and answer. Actually, his answer was just about how feel about my own. It's there, it's like a mouth, it gets wet, and that's about it.
I have in the past been able to get some pleasure out of it, buteven when living as a straight woman, I was always left feeling awkward and empty afterwards. The only time I can really feel anything sexual about it is when there is something in there, but it was never really too good of a feeling for me. I have never had to worry about getting hit in the groin during sports, so that's nice. But, I would trade mine for awkward erections and getting hit in the nads any day. Anyone want to find a brave surgeron and trade?
Us boys here are not the best people to ask, I think we can almost all agree on the fact that we don't want anything down there that is not male. I have had ciswomen tell me that they get the best sex ever; frankly, I find that anal is about million times more enjoyable, offers more sensations, and leaves me feeling actually satisfied. Of course, that is speaking as a gay boy.
