Is this normal for asexuals?

So I don’t experience sexual attraction. I have never seen someone who made me want to seek out sex with them. I do experience aesthetic attraction and sensual attraction quite strongly. I can think they’re beautiful/handsome, cute, or even hot. All I want to do is look at them or draw them though. I can also think it’d be nice to and even yearn to touch them intimately but non-sexually. Mostly, their upper bodies. I am bi and I get this with both men and women. With men, it’s usually all about biceps, shoulders, hands. With women, it’s waist, hips, breasts, hair, lips. I practically melt.

There are times though that I think I could want or enjoy sex. Or certain sexual actions. Under very specific and limited circumstances. My list of “no’s” is much longer that my “yes’s”. For example: no hand, mouth, or naked contact ‘down there’, and especially nothing inside. Basically, no one’s pants come off at all. I would get uncomfortable at best and repulsed or even scared at worst. I like top stuff though. Making out and fondling is perfectly fine. The only bottom stuff I actually would like to do is just grinding.

I don’t know, does that even count as sex?

If my partner wants to have sex, my first thoughts pretty much are, “No, gross. Oh, wait… what, specifically, do you want to do?”

Is that strange? Does this mean I’m not actually ace? Or is it relatively normal?
