What is my sexuality ?

I'm gay I got a girlfriend I'm not sexually attracted to men or women except for her she's the only girl I really love. Also me and her are engaged we have to get married because of baby. I'mso confused though I don't know wether I'm bi or gay or straight. What am I ?

Stop watching porn for a few months and you'll figure it out quickly

Mmmmmm

Demisexual. You're only sexually attracted to people you have a deep and personal connection with. (just a guess :P)

If you're not attracted to any men, you're not gay. I don't understand your confusion.

Do you have to put a label on it?
