Most my time was spent with boys. After being friend zoned by many girls and realising how confusing they were I just lost interest in them. I remeber accidently looking at the Gay porn section, but I loved what I saw. Girls sexually is a 100% nope for me, guys sexually is 1000% yes! I've yet to have any sort of relationship with a guy, but I know im physically attracted to guys and that they are easier to talk to and understand.
If your confused then you just have to experience with your feelings and emotions towards both and eventually you know what you like and love. There's no rush to find out
