Can anyone help me - how can a Gay guy have sex with a str8 woman when he can not get his penis hard?

Here's the better question, why would a gay man want to have sex with a straight woman?

My exact thought..

If you are gay you should not worry about having sex with a woman. My advice is to not worry about the girl and more about the guy.

He probably isn't gay or maybe he is Bi?

It happens all the time. Gay men sleep with women when they are in denial, they have not accepted or do not want to face their sexuality. They use a woman to try and prove to themselves that they are not gay, however they hate the intimacy and you are the one stressing about why they just don't seem to be interested enough. They train themselves to sleep with women but it is so falsed they can only do the minimum, the genuine interest will not be there, it is up to you to be aware enough to discover what is really holding them back!

I have so experienced this first hand. Gay men make great lovers. I was married to one for 5 years. I didn't know he was gay at first. It is hard to live with but if your love is strong enough,you learn to deal with it. We have 2 great kids. We have been divorced for 11 years now, biggest mistake I ever made. Maybe some men try to do make themselves straight but not my man. He is not ashamed of his choice and truly neither am I! I also know that I am the only female that he is attracted to! So who cares, if this is what we choose. He is my life!

If he can't get his penis hard, then a women isn't what he wants.

Some can fantaise about having sex with a man when they are with you.There is also such a thing as incidental heterosexuality whereby gay men sleep with a woman for something different and it turns them on short term in the same way some people enjoy anal sex for a short time or women who dig getting on with a womansexually sometimes.Why do you ask?Viagra is the other answer.LOL.Instant hard-on.

I agree with cshell BTW.Denial can be a factor but why are you asking this question?If you are with a man you think may be having sex with men also but gets hard with you he may be bisexual.
