Between your lack of interest in sex generally (and vaginal intercourse specifically) and your preference to be dominated, you don’t sound like a regular heterosexual male to me (where “regular” is strictly defined by the mode and everything else counts as niche) but your desire (as a man) to be dominated by a woman is a well-established niche, as evidenced by the dominatrix industry (though dominatrices are often associated with BDSM), female dominance hentai and countless other things on the Internet.
Whether you quality as asexual sounds like an discussion about words and not what they’re pointing to.
