How do you get erections on women being a gay?

Ummm...your gay, that means you don't get erections with women. The only way a gay guy can get an erection with a woman is by fantasizing about male same-sex intercourse, but even then, it's not like they would enjoy f*cking a women even with an full erection. I truly feel sorry for any gay person who feels as though they need to live a lie to make those around them happy.
