All right so I'm a 15 year old male, and I've got to problem, and I'm hoping anyone can help, because I'm actually pretty scared about this. I have a sort of lump under the foreskin of my penis, its not red or itches, in fact it doesn't bother me at all outside of it itself being there. I haven't had any sort of sexual activity. Another thing is that before about two months ago when I started paying attention to the bump, I didn't exactly (since I wasn't circumsised) wash or clean my penis under the foreskin, so I don't know if that has anything to do with the lump. The lump doesn't look like a pimple or wart at all, id describe it more as a lump or more spacifically, something circular from underneath my penis going up, but as I said before, it doesn't cause any pain whatsoever. L really hope someone can help me, because I'm scared it could be an STD or something. If it'll help, ill upload some pictures of it, just please, I can't go to my parents about this, and I've done enough research but still can figure it out. Please, help..

You could show it to the school nurse. She wouldn't tell anyone. As a nurse, she would be a better source of information than someone on the internet.

If you haven't had sex, or been in intimate groin contact with anyone, it's very unlikely to be an STD. Both of your parents have seen your penis before. In fact, your dad has one and would probably appreciate you trusting him with such a personal show and tell/question.

If you aren't comfortable coming right out and telling your parents about it you could just say you have this lump in a place you don't think it should be and you would like to have it checked out by your doctor. If they ask where... just tell them it is kind of personal and odds are they will catch on pretty quickly and make an appointment for you.
