This may not seem fair to you, but the point of a religion is often that one must give up pleasurable things in this life to inherit a reward in the next one. Just as the prohibition of homosexual sex exists, there would also be a prohibition against extramarital sex for heterosexual people.
So it goes like this;
HETEROSEXUAL? Sex bad. Unless married.
HOMOSEXUAL? All sex bad. All intimacy bad. All romance bad.
What a cruel god this is. To f-ck up and f-ck with ten percent of his creation. And then to give free rein to the remaining ninety percent to f-ck with them as well.
Your going to have to take your complaints up with the big man upstairs.
If one accepts that God created the Universe, then one must also ascribe to Him the inability of some people to conform to alleged Biblical prohibitions of homosexuality.
