hello.
i've had this bump for over than 7 years that i can remember. i am 18 years old. never had any sexual relationship so far or whatsoever.
what can this be? if that's helpful, i had a small surgery when i was little to cut some of my foreskin.
also i can see there is a slightly white mark on the top of the bump.
Please help me out, I would like to avoid going to the doctor if possible.
This could possibly stem from your previous surgery, but is unlikely. I don't mean this in a bad way but you need 'to man-up' and go get your penis checked out by a Medical Professional such as your Regular Family Doctor.
If you do this - doing things that are uncomfortable for you - the next time you have a similar challenge in life, such as speaking to the person who may be the ideal partner for you, would be easier for you to do.
Go get it checked out ......
