Although I can see the uses in making up terms to define who you're attracted to, I dont like the idea of putting yourself in a box. Ive had straight friends get really confused when they find themselves attracted to the same sex, and gay friends get really confused when they find themselves attracted to the opposite sex. When you "join" a sexuality you dont sign a contract or anything.
A while ago I figured out I was bisexual. It was pretty great for a while, cause I was able to figure myself out and feel more free because of it. I didnt feel guilty for having certain thoughts. However, eventually I started to have some problems with the label itself. In this day and age, what even is a man or a woman? Ive found myself being attracted to people that dont identify as either gender. And isnt gender supposed to be a societal construct? In that case, why do we care so much about it in the case of define sexual identities?
Im no philosopher or social scientist, so I may just be talking out of my own ass here so forgive my ignorance. Nowadays whenever some asks me my sexuality (which by the way is a very weird thing to ask people you just met in real life) I always say "on a case by case basis".
