if your not comfortable asking, while doing your stuff, take a peek up, look at your girls face, when your doing something right youll see the results in her face, dont stare, just a super quick peek, if she sees you looking she may be thrown off, dont make too many noises, dont move your body too much, dont disturb her concentration, dont do the same thing all the time, change techniques remembering from last time the certain things that she liked the last time you did it. also , although going down is considered "fore play" even this "fore play" needs some working up to, women have many erogenous zones, dont forget the inside thighs, ears, toes, belly botton, etc. what one girl likes another may not, its trial and error. just stay tuned to what works. ladies , ok?
