This is an old trick, and it's in a lot of Tantric literature.

Yes, sex is cerebral and I try to be creative, but this shit works!

I have used the 1-2-3-4-BAM on women who have never had an orgasm with intercouse, and they came! I drove my last girlfriend wild with this a few times, and she was wildly orgasmic already.

I have done studies on repetetive music, from baroque ostinati to current techno/house. My conclusion so far is that since our body pulses at an irregular rhythm, the imposition of a regular rhythm, like tribal drums, induces counter rhythms within our body and brain which stimulate primitive desires. Which leads us to the use of repetetive rhythms in religious ceremony, music, and yes (yes, yes, oh god yes...) sex.
