I guess I do not understand what "being gay" may have to do with his singing or if women like him to the point of hysteria. If I am not mistaken, he has something like 4 or 5 kids.
I know loads of gay men who have kids. One of my friends had 5 kids with the same woman and then decided to come out.
I do think that any woman who kisses another guy and is so sexual with him in front of her husband can't really respect her husband, particularly if she does it in front of a crowd of people. So she deserves to be dumped.
