Well, sue me for having too much time on my hands...
I just read this whole thread, and a fine example of repartee it is.
As for my two cents...it would be this:
Gentlemen, if you find yourself lamenting that old Hawaiian disease (lackkanooki) consider looking at sex as if you are some sort of alien, and have no investment in the process whatever, that you are here on the planet to do some form of research on the sexual habits of the female population, and in every encounter, in every possible way, just ASK.
Lower? Higher? harder? softer? two fingers? which opening? like this? how's that? etc etc etc.
Now, before you get to the point where you can ask all those questions, you will have to ask the first one, which is whether she is up for the research project in the first place.
At some point in the research, you are very likely to find the woman will want to do some of her own. My advice would be to LET HER. However, do not become distracted from your project...weekly (or more frequent) experimentation is suggested, and after about five years, you will have as many subjects as you could ever hope for.
Now, before the ladies chime in, let me say one more thing...
I tend to believe that if you spend the five years at the research, you will gradually find that your adolescent proclivity for many partners will decline in direct proportion to the care with which you perform you research. And in my opinion, it isn't about more or fewer partners anyway, that is between the parties involved...I recommend no deception, but again, we all make the beds we lie in...
Ask ask ask ask ask.
She will tell you if you make it clear you are sincere.
All the best.
