Just Do It. Say to your W, "I want to have sex with you tonight!" Tell her you'll be expecting to make time for it. When she says, "uhh, no, not tonight" reply with, "ok let's set a date for it. Tomorrow night would be a great way to start the weekend! If not tomorrow, then I'm definitely attacking you on Saturday." Do NOT ask her for it.
Also, I'm not saying that technique is an issue... but I think you should try something new. I do a "kiss all over" sometimes, where I just kiss my W slowly, all over her body, starting at the neck, working my way down & up each arm & then down her body to her toes on each foot. This takes a good 30 minutes and gets my W "into the mood" for more. Just an example from my world.
