aka you may think these things will make me want to fuck you when, in fact, they guarantee I will not ... ever.

Because you really, really want me to: the more you really, really want it (and I perceive it as the only thing you want that relates to me), the less likely it is that I will want to do it.

Because you act as if you really, really don't want me to: if this is mean to be some awkward form of reverse psychology, know that it won't work. Disinterests isn't a challenge for me; it's simply uninteresting.

Because you decide we will have sex: you don't get to decide this.

Because you show me your cock / tell me how awesome you are in the sack / how you will make me scream etc: I don't believe you.

Because many other women are currently sleeping with you: good for you and for them. That is all.

I may or may not sleep with you if one or more of the following are true (chances of sex occurring between us are about the same as it not occurring):

You said hi to me.
You bought me dinner, movie, drink ... you roped me or I roped you.
We sexted.
We're friends.

Now, if you're still reading this, you might be curious what would, in fact, increase someone's chances of getting into my pants.

The following is a work in progress:

I like you. I don't have to be in love with you, but I do need to genuinely like you as a person. This means that I need to know who you are. We talked. I think you're smart, maybe even funny. You are capable of intelligent, honest, genuine conversation. You've shown me respect and acknowledged, consistently, that I am in fact a fellow human being not a collection of parts.

AND (not or)

I perceive you like me. Again, I don't need you to profess your undying love and devotion to me (that would be very, very bad in fact). But I do need to get the clear sense that you like me for who I actually am. You've shown me attention, perhaps even concern (if appropriate). "Courting" will go a long way here.

AND (not or)

I want to. We have chemistry, both physical and intellectual. You've shown yourself to be assertive and confident, but not a bully; interesting and interested; compelling in your intelligence, but not egotistical. And you smell amazing. You've seduced me - I've felt on the receiving end of genuine effort on your part (effort that was not simply aimed at parting my legs or mouth or what ever).
