If you show sexual desire to a woman, she'll either:
1. Back off in shock because you showed you won't be an orbiter (won't follow your lead) Ultimately she stops responding.
2. Gets closer to you and is happy you just get it! (is following your lead)
If you don't show sexual desire, you are likely to become her friend/ emotional tampon/ beta orbiter/ fallback guy/ attention provider/ ego booster.
Don't come off like a creep, but what scenario is best for you (or any man for that matter)?
I choose the former. Because it weeds out chicks who aren't interested. And we know that uninterested chicks won't have sex with you!
Case closed.
