my boyfriend has something like that on his right testicle and got it checked out. it was just a cyst. the doc said it wasn't related to cancer and he was tested for std's and so was i and we both came back clear.

the biggest thing to look for is change. it's the same with a mole or any other mark/spot. if it stays the same, doesn't move, get bigger, harder or less hard, then you should be fine. but if it grows, gets harder or lessens in hardness or color, thats when you should worry.

it could be something as simple as an ingrown hair that pops up sometimes. i would just talk to your obgyn about it. if you have been tested for std's i wouldn't be too worried.

and never be embarrassed, thats what were here for!!
