Watch the video and maybe you'll understand my position? Women can be in the company of men, just don't compromise yourself around strangers so much so they can take advantage.
Don't send mixed signals around people you trust and more so that you have a sexual history with. It makes it confusing and it sucks for you if your sexual partner gets it wrong?
So its not confusing a woman lets you undress her, have sex with her and doesn't say no or protest? How is the dude acting like an ass when he stopped when you said "no"? He only had sex with the women later coz the woman didn't say no (or yes), left it vague, allowed him to undress her and have sex.
I guess the moral of the story is, if you are going to assume, assume its no regardless how the woman acts unless you hear "yes".
