It's never a bad idea to kick the sex up a notch or ten, either. One of the hallmarks of abundance is you won't care about any one girl and as a result you'll f*ck her, not "make love" or other such phaggotry.
The more a girl is into you, the more she'll do for you sexually. You lead by example. If she's reluctant, withdraw the D -literally and figuratively- and she'll know that the missionary sh!t she practiced in high school won't fly here & now, and she'd better present that sphincter for painal.
F*ck her raw and she won't stay away. I disagree with all the "no porn" wisdom out there. If I hadn't watched so much porn I'd be a pretty vanilla lay, as would most of us.
