Why is rape and dub con is so normalized?

Rape and dub con is so normalized in manhwas and it’s not just BL I would say maybe 90% of straight smut and gl also have a huge issue with rape and dub con it’s just not talked about enough. Like I’m tired of reading the bottom/fl saying “ stop” and “I can’t do this anymore”. Why is it so hard for authors to just write consensual and romantic sex scenes? I can only name very few smut manhwa that actually have consensual sex scenes and where both parties are enjoying it. Idk why people act like it’s only a BL issue like “try begging” is probably the most disgusting manhwa ever created.
