I just go for it.
I set the tone by hugging them real hard so that their titties press against my chest. We're taught to be "delicate" with females, but even they'll tell you that's bullshyt. They love that masculine physical stuff.
If we're watching a movie I usually make them laugh and put my arm around their shoulder.
Sometimes I'll joke around with them and say something borderline offensive and when they giggle on some "how dare you", I'll offer an apology kiss pull them close and nibble their ears, down to their neck slowly. Neck, ear, hip areas.
Obviously I don't handle them like I'm playing rugby, but I'm not physically soft with them either. They're not newborn babies. You're sending a subliminal message that you're in your masculine and can handle your business.
Obviously, I'll know whether the chick is on it like that and not a time waster playing games.
