It’s okay to be confused. I think people tend to link past experiences with current situations and get anxious because they think there’s a connection - it’s not always the case.

To answer you’re question - Maybe. I think sexuality is something that you develop. When you’re born, who’s to say that because you’re a male you’ll be attracted to females, and vice versa - basically it’s a clean slate. When you go through puberty and develop interests in the opposite or the same sex, your personal preference really starts to show. If you had same-sex crushes as a child and turn out to be homosexual, it might be just a coincidence or it might be linked to your childhood experience. This is actually a more difficult question to answer than I imagined. A lot of personal interests such as sports or music derive from interests developed from a young age - not all the time though. To further this, same-sex interests from a young age may very easily carry on and determine your sexuality - or you might have same-sex interests but turn out to be heterosexual. There’s really no way of knowing. I would be of the opinion that same-sex crushes as a child are indicative of future sexuality - especially really strong feelings towards the same sex.

Also, don’t be confused or worried about your sexuality, don’t jump to conclusions and just let yourself feel things. If you know in your heart your true sexuality, be proud of it and embrace it, it’s nothing to be ashamed of.
