What you are feeling is completely fine and you should not worry too much about it.
I'm a 19 year old gay male who is going through something similar to you. I am just recently realising that I am not just attracted to people of the same gender. However, it is important to note what attraction you feel to the different sexes. For example, there is romantic, emotional, aesthetic attraction, and many more different attractions. So you may find you could be romantically attracted to one sex, but aesthetically attracted to to another. It is possible.
And now, I am only finding out that I can see a female as pretty, however I can only imagine myself in a long-term relationship with other guys. That's how I determined that I am gay. However, that does mean that I can also be omnisexual too.
Moreover, you do not need a label to describe yourself, as therising put it, you should just be YOU and you should not have to worry about labels that are constrictive, which is what I found them to be.
Also, I have dealt with internalised homophobia from me. At first I thought I should try to stop being flamboyant because that was bad, but it is okay. In the process of realising that, I found out who I was - someone with a mixture of flamboyance AND masculinity, weirdness, kindness and strength.
All in all, be YOU and I hope this helps!
