I mean honestly I'd probably just give it time. There's no need to know exactly right now what your sexual orientation is. It'd be easier to just stick a label on it and say, "there! That's what I am!" But these things are pretty fluid and, in the end, as frustrating as it is, only you can really decide what you identify as. I had a therapist once tell me I couldn't be gay if I had before enjoyed and reached sexual climax with a man. First of all, that's a very inappropriate thing for a therapist to say, ESPECIALLY if they were not asked their opinion, and secondly, I realized her opinion (which was uneducated, btw) was not valid. I knew how I felt about my sexuality, and that's what mattered.
