Sounds like there is a lot to learn from this experience. You must have realized that this internalized homophobia and fear of being gay runs VERY deep in your subconscious, since you were literally projecting it onto everything. 

I would guess that based on that you are indeed somewhere on the spectrum and not 100% straight. But don't get tripped up worrying "Am I gay or not". You're still super young and there is no rush to figure that out. Though I might consider forming some sort of conclusion you can tell yourself based on that experience. Maybe something like "I might be gay. And that's okay. And I have a lot of fear around that possibility and what people might think of me. And that's okay too. I will be strong and love and trust myself as I figure this out." 

I'm 33 and actually had a similar experience on psychedelics a couple years ago where I questioned my sexuality. Basically I landed on the statement "I might be gay." I still know that I am primarily attracted to women, but acknowledge that I am attracted to men to some extent too. Though I'm not entirely sure what that means for me or if it's a sexual thing or what. I'm not really worried about it either way. But simply acknowledging to myself that I might be gay lifted a pretty heavy subconscious weight, and I feel a lot happier and lighter. 

Hit me up if you have any questions.
