Is it normal to have protuberance around the ?

Yes, it's normal to have a "protuberance" or a bit of extra flesh around the . This is basically just a remnant of extra tissue where that area "closed up" during your development as a fetus. Lots of people have it and it can be of varying size and color. However, it should feel soft and shouldn't have any pain. If it's hard or it hurts, you may want to get it checked out, as this could be a sign of an abnormal growth. Otherwise, you're fine.
