What am i?! Gay, Straight, Bi?!?

So i hooked up with my best GIRL friend on new years eve this year. and ever since then i have been interested in more straight relationships. i have been openly gay for almost four years now! Holy ****?! Am i turning straight? My other friend that is a girl, is dating a guy and when she told me she was dating him, i kinda became jealous. and now i am having feelings for her! but just a couple of hours ago i had a guy blow me and i liked that! but i hated blowing him! but i love eating out!? holy f balls!? are other guys having these fluid sexual feelings? should i come out as striaght?! i know about alfred kinsey's scale of sexuality, so i know that these feelings are normal. its just i always thought i was a 6 or at the least a 5 on that scale! wtf!
