16 year old boy, Don’t know if I am gay:

So I always was positive i liked girls until the beginning of high school last year. I Hooked up with a girl and really liked it, and was very aroused . Soon after i started getting curious about how big my friends dicks were and sometimes if I saw one of my friends dicks then I would get a boner. Also I am attracted to male masturbation but the idea of gay sexual intercourse doesn’t really arouse me. I still get aroused by my friends dicks but I also still like girls and deep down one day i want to marry a girl and have kids. I also don’t really have a crush right now so I really don’t know my sexuality and I’m scared, also all of my friends are homophobic so I don’t even think i could come out yet if I figured out I was gay. What do you guys think my sexual orientation is?
