I don't regret it. I've had sex with 18 guys. Some more than once, some just once. I like having sex and it makes me happy. But lately I've had sex with a lot of different guys (8 different since May when I broke up with my ex), and I've noticed some of my friends have started commenting on it. It kinda annoys me. I'm not going to change my lifestyle, I just need to know if this is something I want to keep from my friends. So... is it?

Plus, hiding it from friends implies she's ashamed of what she's doing. So, if she's not ashamed, she shouldn't keep secrets. However, there's no need to advertise it either. :)
If it walks like a duck and talks like a duck...
It's your life no one elses. As long as you feel good about your choices(and keep yourself safe), I don't see anything wrong with it.
Your comment made me feel better about it. Thanks!
