Still really just comes down to how you carry yourself.
You can still be jacked and be desperate, a douchebag or just very unsure of yourself women can smell that a mile away.
People want what they can't have, and nobody likes to be pressured to do something.... even if they WANT to do it.
I just figure I set my mind on having a good time, don't put any girl on a pedestal, talk to them like they're your best friend (without the vulgarity), and chances are she'll come on to you before you even have to mention or hint at sex.
Just gotta have the confidence that you don't give a shit either way if this girl likes you or not because there are 100 others that will if she don't.
