A man can get hard and ejaculate even during rape,

Asexual men? I thought having a sexual response when you weren't mentally interested was due to your body being sexually stimulated against your will. But here it would be a willing man with no sexual interest being sexually stimulated...

Eh, whatever, it doesn't really matter what you call it, but it seems silly to me to call it "asexual" if you have a reproductive system, since technically you are a sexual being, even if your libido is low and you don't feel attracted to anyone.

Plenty of people don't have a lot of sex at various points in their lives. It's a stereotype (based on something) that couples stop having sex once they get married or have kids, for example. Older people can stop being very interested in sex. Depressed people can lose their libido. Not everyone is constantly doing it.

But actually asexual would be a robot without genitalia. Otherwise you're a sexed being.

If you are interested in a partner you're oriented toward some type or other.

If you ever think about non-platonic touching (intimacy you would enjoy with your partner but not with your parents) you have some level of libido, however low it may be.

If you're a sexed being with no interest in a partner who has never thought about private touching at all, my thinking is that you have somehow never fully physically matured and I wouldn't put a label on it yet. But everyone's different and if you're happy there's no need to force anything. I'd still call it nonsexual rather than asexual since asexual implies not having a sex. Still, given there are a huge range of levels of sex drive, and they change over time, age, circumstance, surrounding people, mood, etc, lots of people go through periods not thinking about sex, I wouldn't be certain it's so black and white. Probably a low sex drive, not with the right (type of) person, and/or with other things on their mind.
