I am a 23 year old girl and I am virgin but my boyfriend is fingering my vulva(not vagina, upper side lips) since past four years and now it has become a quite frequent practice. We are not planning to make out till now. So is this fingering gonna affect our sex or child birth? because now I have started getting pain in my stomach just after the fingering which I nvr had before. please help me with this, I am damn confused..
