Committing To Mitzvot As A Gay Man

The idea of conversion has been swimming in my head for a few months now, though I have yet to take a class.

I'm looking at either Conservative or Reform because I don't think I could adapt to an Orthodox lifestyle. With that said, I would want a halachic conversion, which means accepting all mitzvot, including the ones that prohibit male-male sex.

I am a gay man and while I don't have a particularly high sex drive, I'm not celibate, either. So there's my dilemma. I don't want to lie during the conversion process, but I don't think I can accept a commandment that prohibits me from having sex. I'll feel like an imposter.
