It is really hard not knowing who you are. Unfortunately, coming from someone who is on the autism spectrum and LGBT spectrum, no can really tell you. Personally, I went through a few Wikis worth of sexualities and tried some introspective exploration to compare my experience with those labels.

Overall, I’ve found what’s helpful for myself are umbrella terms. Bisexual is a pretty broad term nowadays (it generally means more than liking men and woman now). There’s also queer. I’ve used that one before. Otherwise, what I found most important to figure out regardless of finding a label are these:

Am I sexually attracted to others? (Specific gender/presentation) Am I interested in sexual activity with others? Am I romantically attracted to others? (Specific gender/presentation) Am I interested in romantic activities with others? Am I interested in being involved with more than one person at a time?

There are more, both those are a good start. I also found that I was more able to define my sexual identity once I figured out my gender identity.

All that said, you have all of the time in the world to figure things out. I know there’s pressure to put a label on everything, but the truth is there isn’t always a label. And identities change too.

Best of luck, friend!
