Ok Wonderer.
I completely agree with you that sexual technique (which is what you are trying to perfect here i assume, by finding out what women want - no pun intended) is super important... who wants to sleep with someone who's no good at it?? but in this i can only speak for myself - other women may be with me here, but even so, its only SOME women. Every woman finds pleasure/cllmaxs in a different way - some from oral sex, others from penetration - some dont cllmax at all (*shock horror*). It all depends on the responses that a particular woman has learnt to enjoy... i am terribly afraid to tell you that there is no list i can give you of what women enjoy. Penis size depends on the woman too - does she get off on the feeling of a penis inside her?? could be that a fatter one is better, or a short one, or a slim long one. It all depends on what she likes. Your best bloody bet - like everyone has been telling you - is to ask the woman you are sleeping with. Chances are she will tell you. If she doesnt, keep asking.
As for the lust/love debate; some women do enjoy the pure animality of sex, but i dont know anyone who enjoys it all the time.
hope this helps dear!
