me and my gf are laying down on the bed. i want to get into her pants. i slide my hand down her belly and when the tip of my fingers go under her pant line i move my hand from one side of her hip to the other. then i slowly move down further but the she stops me and pulls my hand out b/c it tickles. how can i get around her being "tickled" or is it just an accuse that she doesnt want me to go down there?
