My (now Ex-)boyfriend and his friends talked about a girl who had apparently slept with several men and was therefore a slut in their eyes. I told them they were hypocrites for praising men who slept with a lot of women but shaming a woman for doing exactly the same. They just laughed at me and said “You see, a key which can open many doors is a great key. But no one wants or needs a lock that can be opened by many keys, because that’s a shitty lock”. Now I seriously regret not dumping that guy on the spot.
