Unarguably, I still have things remaining to learn about sexualities and how people's definitions of them vary, but I believe they're all valid orientations. Wouldn't uhm, though, pansexuality and asexuality conflict in definition? Pan means an attraction to all/any genders, while ace is no kinda attraction to anybody, like the antithesis of a neodymium magnet. Unless you mean panromantic? Panromantic + asexual is totally possible and good..!
