The reality is that from listening to a lot of bottoms, they always say that when someone labels himself as "versitile" , it means that he's really a bottom but internalized homophobia won't allow him to admit it to himself. Secondly, these same bottoms don't want to encounter someone who might want to be dicked in return. Since the bottom likes only to be fucked, he cannot comprehend when someone truly likes both. So in their minds, "versitile" means closet case bottom, because in their minds, that's all they know. Yes, it's an evil and petty world out there.
There's too many other cool guys out there, so I won't even bother with a bitchy bottom who has a laundry list of what is acceptable. It's about as offensive as the guy with racial requirements or dick size requirements.
