How cum tributes are categorized

I find it weird that in order to tag my tributes as "cum tributes" I can ok only choose an option from the "gay" content categories. I'm not offended but I'm also not gay, none of my tributes feature gay men. Most , not all but a good majority of tribute online Xhamster feature men cumming over females. I get that there are gay men who get off with these vids, I just find it funny that it's considered an exclusive gay category.
