Can a gay man married a woman?

Yes, so called "companionate" marriages used to be quite common back when being a gay man was a problem for guys. Wives used as "beards" is a tried and true ruse men used to have to use to stay employed and in some cases to stay out of prison.

Some have. But living a lie is not a happy place to be. Most eventually cheat to be themselves, and it ends anyway.

He can, but what would be the point? the woman wants sex with a man so does the man!! waste of time and will make both of them unhappy.

happens all the time.

Not really sure about it...once he sucks dik and balls and take it from behind I don't think he can pound pu SSI hole

A lot of gay people enter a heterosexual marriage... to hide it. Their spouse may or may not be aware of it.

I worked with a "couple" years ago that both of them were gay, yet married.

Sure, get her a big vibrating dildo and she'll be fine.

He can but it's not going to be a happy marriage
