I think I'm sexually attracted to females, but would never date one. I'm both sexually/mentally attracted to males. Sometimes I question the gender thing. I'm just rather confused(cis female)
I am far more sexually/physically/romantically attracted to female/feminine/gender fuzzy folks and way more likely to engage in a relationship with them than I am with male/masculine individuals, but not exclusively so. Having some variance in who/how you might engage in different behaviors and relationships is perfectly reasonable. We are all complex people with complex desires and both gender and sexuality are spectrums, not fixed boxes you check off.
Chances are you are something like a Kinsey 1. And that is just one potential way of describing things. But you are certainly not alone in those feelings, and you should absolutely not feel any shame about them. Be honest with your partners, and do what makes you happy.
