Christians: please help me here?

I am struggling so bad with this issue. I am so sick of seeing men degrade women and call them names for sleeping around. Well a lot of men that call women names are sleeping around themselves. That's a sin right to sleep around when not married? Fornication? So then why do men feel they have the right to judge women who sleep around because in a biblical sense they are both sinners for sleeping around and both in need of repenting. So why does society glorify a man and say "high five man you got her nailed" when in all reality he is a sinner to and so is his supportive friends. That bothers me so much is how a sinner can condemn another sinner who is lusting and having sex just like he is. Am I right?
