I don't think there's anything wrong with casual sex as long as everybody's an adult and clear about what's going on. It's not for everybody, obviously. Nothing wrong with experimenting, but just be sure you're ready for possible consequences. And use a condom (and it's a good idea to use another form of birth control as well)!

I have a problem with terms like "slut" and "skank". First of all, they're almost always directed at women, because we still think men are studs and women are sluts for having sex. Why is it so bad if you enjoy sex? Even with lots of partners? I wouldn't dump my best friend (or any friend) because they're more sexually active than I am, or choose multiple partners. As long as they're not sleeping with my guy (I like having one guy, but I'll admit to being curious to try a threesome someday or other fun stuff), what do I care? Of course I care about my friend's health, and if I feel she's doing something dangerous and unhealthy, I will tell her, but I will also support the decision she makes.

Sex shouldn't be seen as this taboo subject that it is. It's a normal, healthy part of being a human. Now that we have talk shows and books on sex, more people can get answers to their questions, when one time years ago, they'd just suffer with the problems they had. I believe religious and cultural beliefs have skewed sex and how it's accepted (or not) in society. I don't mean to offend anyone by saying that, but that's why sex is viewed as it is.
