People have sex with people of the same sex for their own sexual gratification, there's no God involved in that. You want to ejaculate, and women want to reach orgasm, that's why you have sex with another person of the same sex. You are not doing God a favour, you are doing yourself a favour. Other people have sex with objects like vibrators and I can assure you that God didn't make them to have sex with vibrators. The reason they are having sex with vibrators is to satisfy themselves, the same way you satisfy yourself. Or did God create vibrator-squee human beings as well?
Don't fool yourself, you know very well you want satisfaction out of your own selfish heart. The same way other people want satisfaction from little children, or Michael Jackson with little boys, or R Kelly with tweens, or some sickos with animals. God didn't create you that way, you are just addicted to sin and sin controls you life. That's where Jesus comes into the picture, He wants to relieve you from sin slavery. You can be non-gay again, like Adam was!
