Sexuality Help

I have a question.

I have up to this point identified as pansexual. But now I'm kinda confused. Is it possible to feel demisexual towards men and not towards any other genders? I think I feel attracted to women when I don't know them that well, but I think I only like guys after I get to know them better. Is that possible or am I just over-complicating things?

I'm a baby gay I'm sorry if this doesn't make sense
