I need to define a few terms - if you are dating someone, and you aren't exclusive and see other people, yet have sex with them, at what point does 'dating' equal 'promiscuous' ? Where do you draw the line?

Promiscuity can't really be defined. It's a personal decision that you need to make for yourself. If you think what your doing is wrong then it is. However if you are happy to date or sleep with several people and you are practicing safe sex and no one is getting hurt then that is your decision

Very well put englilshrose! I think if you talk to the person that your seeing/sleeping with and everyone is informed of what is going on then there shouldn't be any issues. But if your lying to the person your "sleeping with" and telling them they are the only one, then that isn't right.
