But not this century. That's how long it's been since I've had sex with anyone other than my hand. I've begun to think that many men turn to being gay or bisexual just to have some contact with another human being. And it gets more difficult as we get older. Few young men want anything to do with an older man who has a beer belly or doesn't have a slim body with no wrinkles. The older men quite often have a hard time getting an erection. Is that why many older men turn to being bottoms?
