Butchfemme and inherent eroticism

(Reposting this because the previous one got automatically removed? For now I'll assume it's because I didn't add a NSFW flair).

I've been trying to look into what it means to be butch and the dynamics between butches and femmes. I've seen a good few people online w plenty of likes about the "inherent eroticism" or the way sex is a large part of being butch over being a protector. Is there any precedent from history or something on why people believe this? And what does that mean for the butches/studs who are also ace and/or sex repulsed? I'm seeing a lot but I don't exactly know what to believe about it all, currently.

I'm trying to figure out myself as a person as I read these types of posts (my gender, sexuality, if I am ace or not etc) so I guess I'm just trying to make it all make sense in my head.
