Hey I am 17 recently I have been having some nipple problems no pain or discharge however they have grown and the nipple seems to have "come out " is this a result of sexual activity with my boyf he has sucked on them 4-5 times but not for long , will they return back to normal if he stops ?
He also fingered me is their any chance I could get preganat?

If you are seventeen and you don't know if fingering will make you pregnant, then you had better take some classes for the 'birds and the bees'; or ask your school nurse for some advice or booklets on this subject.
