I mean, I wouldn't consider hooking up behind a bar or in a park the same as breaking & entering into a vacant mansion.
You could totally be right that this is what occurred, but I don't think you're correct on how young women just do this all the time. It comes off condescending and sexist, in my opinion. Like girls are dumb and will just go anywhere with anyone to hook up... no. Of course, some girls would, and so would some guys. But, many girls would not. Especially at age 24.
Have you ever heard of the book The Gift of Fear? Trusting your gut instincts is something most women are encouraged to do starting at a very young age, because the world is dangerous, especially for young women. None of the 20 somethings in my life would break into a vacant mansion, or follow others into a vacant mansion, to hook up with someone.
