Does Yaoi romanticize toxic relationships?

Ever since quarantined started, i've been reading a lot of manga on here, and it's kinda made me realize something. Mayyyybe I'm speaking really broadly here, but in the most yaois i've come across, the sub is almost always saying 'no, stop, slow down' while the dom is always just not...listening?????? Like everything is just borderline non-con, with most being dub-con at best. I really wish there'd be more tags and warnings for these type of things.

Is this true for straight manga too? But like most of the straight (nsfw-related) manga I've seen have shown both the women and man 100% consenting.

And I knowwwwww 'they're fictional characters, they're not real' but it STILL would be nice if yaoi/other creators put warnings in their stories.
