I really hate the word "slut." Men aren't sluts, they're studs. Women shouldn't be ashamed of enjoying sex and exploring sex, and while I'm not suggesting it's a good idea to be promiscuous, one shouldn't be labeled "dirty" or a slut for it. Especially since many people who behave promiscuously do so because of past abuse or rape, or low self-esteem. Calling such a person a slut is like kicking a person when they're down.
