For the past month; I have been questioning myself, I am unsure as of why; but I am. I question myself because recently I have been questioning my past and reasons as to why I never approached any of my crushes on the women I liked. I never felt like I actually needed to for my sexual health, I also questioned if my feelings towards them, as I currently have one on another woman. I never had no sexual attraction towards men, I even experimented when I was a kid (or it would be considered such by today's standards). We did not do penetration but we rubbed up against each other, and it did not get me hard or anything. I normally got hard in the presence of a hot woman, and still do as far as I am concerned; hell I even got hard when I was checking out these two female Wal-Mart workers, I found them very attractive and even had some naughty thoughts, but even then; after I think I have myself figured out (I'm probably a hetero-romantic Asexual or Hetero-Demisexual, not entirely sure), I still have the constant questioning and unwanted as well as intrusive sexual thoughts of men, they do not turn me on or excite me, they just scare me. Not because I have a problem with homosexuality, but because I am seeing things I don't really want to see, I mean sometimes the thought comes into my head and I'm just like "Ew, Why brain, WHY!?" And no matter what I do to show and prove my sexuality to myself (I don't have a problem with being gay if I was, I just got a problem of finding what my problem is, because these questions and unwanted/intrusive thoughts annoy me, instead of turn me on). What is wrong with me? It is interfering with my life a quite a bit.
Remember that simply having homosexual or homoromantic fantasies or mental images doesn't necessarily mean you are gay. I'd believe it to be natural for the mind to 'wander' in that regard, even after youth. Based on what you've said, I'd characterize you as heterosexual given you demonstrate attraction to the opposite sex and not to the same sex (or, if you don't have sexual attraction towards the opposite sex but rather a strictly aesthetic or sensual attraction, you're a heterotomantic asexual as you've stated). However, don't get to caught up in labels. They often times are ill suited and are more 'comfort terms' used to qualify a vast multi-tiered spectrum of physical, romantic, and sexual attraction. Don't be bothered if you can't 100% declare yourself a particular orientation. There's a sizeable crowd in the exact boat who still manage to have confident relationships and social interactions.
