Do you find it normal for a man to fuck another man in the ass? If so then you have serious issues.
Lonestar, I want you to be open minded and I want you to try something either by yourself or with your spouse the next time you're having sex.
Stick a dildo in your ass, move it around a little bit and keep doing it until you orgasm. I guarantee you that your orgasm will be about 100% more intense than anything you have ever felt before.
The idea of having something stuck in your ass to get off isn't what homosexuality is about. Lots of straight people, including myself, enjoy that because all men have a prostate gland over by there and it's the male g-spot. So all gay men are doing is stimulating the g-spot with a penis. I've had it done with a finger and some other objects that we won't go into.... and it's been AMAZING.
What defines homosexuality is the attraction to a man, his personality, his essence -- everything about him. It's not just sexual. It's emotional. If your wife died tomorrow, God forbid, I'm willing to bet you'd feel emotional because you love her. It's the same way with homosexuals -- they love each other. Something in them makes them be more attracted to their own sex than the opposite sex. And frankly, most of them lead happy, productive and normal lives.
