You are right about that, I had a beer with a nephew of mine and his friends, they began talking of their conquests, and not only shocked me, but embarrassed me too. Now I am no prude, but the commonality of experience was amazing between them, and they thought nothing of sharing the same "girlfriend"????? Since that time, I have seen that this experience that they related, was not only common, but seen as normal by the females as well. I guess dignity and self respect are mores of the past.
Oh my gosh! That sharing girlfriend/boyfriend thing just gets me! In my world, if a friend was with a guy, you avoided him. Period. No matter how cute, no matter how much you liked him. It was just GROSS to be with someone your friend was with. Not anymore. It's like a big swinger party in high school and college. Dear God. I have three daughters. I'm scared.
