I find both men and women attractive in their own ways, but I could never see myself dating a woman. I want a boyfriend. I don’t look at romance games or stories where the protagonist romances a girl either because it’s not relatable to me. Only men. Do I just prefer men or am I just straight?
I you find both men and women sexually attractive I think that’s the definition of bisexual. Even if you never act on that attraction or you don’t feel romantic attraction to either men, woman or both.
There’s a gap between sexual attraction and romantic attraction. We can feel sexual attraction to people we don’t feel romantically attracted to, and the other way around.
If we want to go down the terminology rabbit hole I suppose the term would be heteroromantic bisexual.
