Open relationships and hooking up.

What is your opinion on open relationships, or hooking up? Is it bad, or good? Is it really damaging to women? Damaging to men? Would you have casual sex? In my opinion I don't think there's anything wrong with an open relationship, or hooking up as long as the person is honest with themselves and the other person about what they really want. Also if they use necessary protection when having sex.

I don't know why this thread has no attention.
But I do admire people who have needs to share them with other compatible people who also have needs.
The only thing is, most people are afraid to try this. That's all.
