My boyfriend and he was playing with my nipple and he was sucking it and rubbing it and when i left i noticed splits & scabs on my nipple, help?

His sucking dried it: hi, Libby. His sucking temporarily dried out your nipple. The same thing happens in early nursing. Might try some vitamin E or neosporin to keep it moist and to help in its healing . And ask him to be a bit more gentle next time. If it doesn't improve in a few days, you need to see your doctor.

Mild trauma: May apply apply Vaseline to it. It will heal.

Nipple: Local soothing agent such as Vaseline, and keep area clean.
