I'm a big fan of pinching a woman's nipples. Once I had a girlfriend, who also liked it, to get her nipples pinched and squeezed, but always made me stop when it get to hard, while for me this was just when the fun started... She then said, that if I pinch them to hard, they could get hurt and it later could be a problem, when she wants to breast feed a baby.
Does anyone of you know, if this is true? Is it actually a problem or just a bad excuse by her?
