Everytime I finger my girlfriend it tickles her a lot, is this normal?
Yes, it is normal and it is perfectly fine to laugh while having sex. In fact, laughing during sex enhances it, in my book.
copy and paste:
omg I tickles because its so sensitive if you keep doing it she'll orgasim in no time
Of course it is!
I giggle a lot when my boyfriend fingers me.
HAHAHAHAHAH wow im sorry but I nvr heard of that before. I don't know??
