Have the goal of having sex with her as an explicit one. Not in the sense that you tell her spontaneously, but that you're not hiding your intentions. This is, after all, the purpose of your pursuit even with the routine. The difference is that with the routine, your objective is to hide your intentions with the guise of an innocent massage. Authentically you wouldn't feel the need to mislead or hide your intentions and could progress to having sex with her via the moment and without the need for premeditation. I don't think people are advising you to tell her that you're having sex or be crass at an inopportune moment in order to prove your masculinity and woo her to the bedroom.
