Watch for the words "blue balls" - they're a red flag. A scam that men learn in their teens, teaching women that "if I don't have sex within a certain period of time, it causes physical pain." A lot of times it'll be proposed as the girl's "fault", combined with a backhanded compliment/rape apology argument (i.e., "if you didn't turn me on so much, it wouldn't hurt this bad to wait").

It's all bullshit, of course. But I continue to hear men (and women!) mention "blue balls", or similar "medical conditions", as legitimate reasons for agreeing to have sex despite not wanting it.

(Yes I have posted about this before, but it deserves its own thread I think)
