"Look. There's one thing I want to make sure you're clear on before we go any further... Are you listening to me?!"
"Yes, yes. What is it?"
"I'm a slut."
A wide grin creeps across his face.
"Yeah, you like it now. But you might not like it later. I've been through this too many times. We'll have sex tonight and then you'll want to continue having sex and before you know it you're telling me you love me. There's nothing wrong with that per se. I love being in love too. But unfortunately, for most guys being in love makes them very insecure. When guys get insecure, they want to start controlling their partner's behavior. The next thing I know you're telling me that I'm not allowed to fuck other men.
But here's the problem with that attitude. It's based on the assumption that I'm fucking other men in some kind of try-before-you-buy plan and when I find the one I like the most, I'll commit to him and dump the others. But that's not what I'm about at all!
I'm a slut! That means that I get off on fucking different men every night. That's what I enjoy. So I'm just telling you now so that you can do or not do whatever you want with me, but keep in mind that no matter what I will always be fucking other men. So you have to be somewhere between 'OK with that' and 'a pervert who actually gets off on knowing that his girl is fucking other men on the nights when she's not with him'. So now what do you want to do?"
