According to your thought process, it's ok for men to sleep around but not for women because it's "instinctive".
Since it's instinctive for humans to want to reproduce at the age of 12 or 13, I guess we should see more middle schoolers knocked up.
Since it's instinctive for humans to be hunter/gatherers, I guess I should go kill the cows in the pasture down the street and bring it home for my roommate and me to dine on instead of going to the supermarket.
There are plenty of other things out there that are instinctive but what makes us modern-day, mature, human beings is that we can curb all these "instincts" and desires and be productive citizens of society. Calling a woman a whore for sleeping around (or saying that even those who don't sleep around are still whores) is wrong and I think it's lame to try to back it up by saying it's ok for men to do it because it's instinct. I personally would never be with a man who made it his goal to sleep with every girl he meets at some shady bar and I'd laugh in his face if he said to me, "Baby, it's ok that I sleep around. I'm not a slut. It's just instinct!"
Inherently, women don't always want to have sex? Hah. We do always want to. We just tend to shut certain men out when the sex is bad.
Furthermore, I'm sad this thread has turned into another women-bashing thread where we've degenerated into calling all women whores and, once again, praising men who sleep around. I've gotten PMs and reported messages about this thread and, quite honestly, I'm sick of being called a whore just because I'm a woman. I am FAAAAAAR from being a 'whore'. If the discussion continues that all women are whores, I'm going to take out a big old lock and attach it to this thread.
Let's continue with the original intent of this thread which is 'Love Online'.
