What am I?

Tbh I'm am very confused about my sexuality.At certain points I feel attracted to men, but when I think about doing anything it kinda turns me off. While with women I feel like I really want to start a family and have children eventually, but just thinking about doing anything doesn't feel right either.My girlfriend broke up with me and said it was due to stress in her life, but I have a feeling it was because of me since I never did do anything for 8 monthes because I was and probably will always be scared and nervous. I did not even give a kiss.I'm also not old enough to really do anything yet since I still am in high school. However, I do mainly prefer gay porn, yet I can totally get off on straight porn too.Most the time I feel more of a emotional/personality based attraction rather than sexual attraction with people that I know.
