first of all u dare to even stick ur face down there anot? many
guys cannot "tahan".
and licking alone is sometimes (usually) not enuff to get them to
climax. depends lar.. some gals can climax on clitoral stimulation.
some need only vaginal, some both, some cross legs can cum
liow.
best thing is to explore ur girl together. communication. dun be
shy. every girl is different, there's not "one size fits all"
manual on how to pleasure them.
