See a doctor right away.
No way
he wanted a reason to bump into you:] hehe
That he didn't mean to bump into you and wishes to apologize for his being clumsy...
allow your friend to bite on nipple like girls and kiss your friend
yes
The description "ball" is somewhat vague in this context; if you are overweight you could simply have a fat deposit on your chest, or if you are muscular it could simply be your pectoral muscle; it is also possible that you have developed a cyst or a tumor (in which case you need medical attention). If this ball is larger under one nipple than the ball under the other nipple, that would suggest a medical problem.
yes it does by:chris
It is possible you just need some testosterone cream to rub on your nipples. Why not see a doctor.
You should probably get that Checked out!
It could mean that he was startled by the near collision and wanted to see who was behind him. He may also have wanted to make sure you were okay after the almost-bump.
A boy skink will have a bump underneath the tail a girl will have a closed up hole
