Aint nothing wrong with same sex marriage. Two people that love each other, simple as, gender should have nothing to do with it.

As for gay sex, in my opinion (18+) penetration in the anus should be seen just as oral or intercourse, yeah it's a bit more dangerous and probably uncomfortable, but it is all sex at the end of the day, regardless.

It is kind of strange how people these days see same sex marriage as wrong or unnatural. Most people don't believe in God or are atheists, yet choose to believe marriage should be for man and wife only as God, who they do not believe, wanted? Wierd.
