Sex-repulsed? Ace?

So I just learned “sex-repulsed” was even a term & I’m really not sure whether it applies to me? I have had sexual experiences, but only leading up to vaginal sex! I have always been down for oral with my past male partners, but as turned on as I am, i get turned off when they suggest sex. Not like I’m consciously telling myself don’t have sex, I guess my body just does not want a penis inside me LOL. I have had this experience on several occasions, except one. That particular time, I did want to have sex with my partner, and in all honesty, he is the only person I have been sexually involved with that i had real feelings for, and maybe that’s why I was so down in the moment? I haven’t identified as demisexual for a long while, but maybe that makes more sense than the sex-repulsed idea because I’m not repulsed by all sex? But I have had solid fwb relationships, no feelings caught at all… Maybe I’m just a really complicated human being, but if this makes sense to anyone please let me know. Thanks!
