Agree I have had two ex girlfriends who really got into pleasing me not as a duty but got workup big time. Makes a gigantic differences in how exciting the experience is.I also think the inverse is true as well. Even very attractive women who show little to no interest in sex besides what is just expected of them in a relationship and never express desires, fantasies and show willingness to be attractive to other men, just don't make me want them at all. If that inner flame to sex is never developed or shown, it's a big turnoff.
