Question! Hi Dr. Doe, my partner and I really like rough sex. I frequently ask my partner to pinch my nipples hard. I feel a little bit of pain, but only in an arousing way. My partner say that he is applying quite a lot of pressure. So much that if I were to pinch his underarm as hard as I like ny nipples pinch, it would definitely hurt him (not in a pleasurable way). My partner and I wonder if nipple pinching could lead to future problems later in life especially when breastfeeding.
