Most western countries used to ban homosexuality too, but people still did it.

The gay guys I know here *love* it. All guys, hardly any women, most of the clubs only have guys in them, you can go to cafes and restaurants and movies with other guys and it doesn't look strange, and you can even hold hands in public and it's acceptable.

It's a personal choice of course, but my gay friends have lasted much longer living in Qatar than straight people, and they've all had a great time.
