Well, as a gay man who does not have a G spot I'll do what I can. Not all men derive pleasure from prostate stimulation, only about half of the male population. And this has absolutely nothing what-so-ever to do with sexual orientation. Take me, for example, I'm as gay as they come, but the pleasure I get from anal penetration and prostate stimulation is so slight it is almost non-existent.

On the other hand, I've fucked a lot of men in the ass who gave ever outward indication that they were really enjoying it. Some of these men even reached an orgasmic climax while I was fucking them with little or no stimulation to the penis. And a lot of these men self identified as straight.

It all depends on how the man's body is built. He can be totally straight, but if his body is built so that he derives pleasure from penetration, he will enjoy being fucked.

As for your situation, start with your own finger to find out what feels good. If this works, try a dildo. If that works, broach the subject with your girlfriend. You'd be surprised how many ladies mount their boyfriends with strap-ons and fuck them silly. And this does NOT make these men gay. Any sexual activity between a man and a woman (no matter WHAT it is) is heterosexual sex.

So if you want to take it in the ass, go for it. You might be one of those lucky men who can get off this way. Others have told me that the orgasms are indeed amazing.

Ive orgasmed while sitting on my 9inch dildo shots of piss and cum felt awesome
