OP, now I have read everything here and in the other thread of yours.
I don't know about the other DJs on here, but from my own experience, 3 (three) dates are maximum time for sex to happen. If, for whatever reasons, I can't fvck her at the 3rd date, then 99,999% I never will because her Interest Level in me would drop close to zero by then.
The fact you prolonged the entire courtship to the 5th date means you need to learn a lot more about the art of escalation, OP.
Remember: Whenever you fail to fvck a girl, she'll find another guy to do it for her.
