Unsure of my sexuality

[justaguy]

Hi, I'm new to this forum, main reason i decided to join was to ask for some help. I am currently 17 and unsure of my sexuality. I had a gay experience when I was 15 with a boy and did enjoy it however, after that I got into a relationship with a girl for a year and a half and did enjoy that ALOT. After getting my heart broken etc, I got a new girlfriend but wasn't really feeling it. I'm really unsure on my sexuality and think I may be bi, I do like both types of porn with gay and straight but I feel myself preferring men more than women, but at the same time I really want a heterosexual relationship, have kids etc. I don't quite know if there's a way to be certain or if I'm going to be unsure rest of my life, was hoping I could get some advice on finding out about my sexuality and dealing with me confusion.

Any help or advice would be appreciated thanks.
