I saw it in another post and found it interesting because in my case, being 22 years old and having had quite a few female friends, it's something that can be defined as quite common, especially during adolescence when hormones are at their peak. In fact, I have many memories of female friends telling me verbatim that they've had a "slutty" phase where they hooked up with anyone and everyone and had sex just as frequently. They were always well-integrated and sociable girls. The less popular girls I've known haven't gone through this "phase".

In my particular case, I've met more women than men and have avoided befriending guys who were too focused on hooking up, so I can't speak on that front. What are your experiences in this regard? Is it a phase that occurs in both sexes? How common is it?
