People can get mad at me but...

Monogamy is un-natural anyway. You don't see animals in the wild just having sex with one animal do you? Like... chickens have lots and lots of sexual partners! So do monkeys! And so do sheep. Animals copulate with many other animals.

It is just un-natural for one person to have sex with just one person for the rest of their life. It is wierd.

Likewise...

It is wierd to just have sex with your girlfriend if someone else offers you something so nice This lesbian chick is really pretty and I am looking forward to next month and, yeah, she knows my no-condoms policy.

I would regret it for the rest of my life if I said 'no' to her, so, really, I have no choice I don't want to have regrets anymore!
