I agree. Then, where is the line? What is considered to be ok and what not?
It didn't become clear to me, about what concrete behavior the OP is talking about.

I have to admit that until not that long ago I abused sex as a kind of pain killer, just like alcohol, nicotine and the like. Means, often I didn't want sex because I was in the mood for it, but because I just wanted to get carried away. That's something that probably doesn't go unnoticed by the partner.

Just like when someone (99% men) is desperately looking for a one night stand and it could be almost anybody who just isn't grossly ugly or disgusting. Like a piece of meat that is just barely doable. This rarely goes unnoticed.

The opposite to this (been there) is when the woman (in most cases it is the woman) just doesn't like sex and considers it only as chore to keep him around and/or uses it to educate and discipline. "You've been a good boy all day. You did the groceries, painted the fence and fixed the computer. Good dog, here's your treat - you may now use my vagina for 10 minutes. Wouldn't mind though if you could make it only 5". Very frustrating. A woman who likes sex and doesn't mind to say it beats that any time to me.

But anyway, the question is what exactly is supposed to threaten men?
