When the guys I know have been behaving this way, I haven't exactly been endorsing their behaviour. Especially if they act like apes. And there is a difference between the genders and sleeping around and then bragging about it.
People treat women differently regarding this. That's a fact of life and life isn't fair at times.
I've actually told women this over time and remind them that a man can sleep around and he's a stud. People will cheer him. A woman does the same and she's condemned. Women are held to different standards when it comes to sexual behaviour and there are consequences when they begin to act like men.
I really wonder why more women haven't learned this lesson by now.
Something a good deal of women I know are utterly clueless about. They honestly can't understand why the men they put out so quickly to have such a low opinion of them. And from the sidelines, I just shake my head.
