I have had white bumps on the front-underside of my penis head since I was 13 (I'm 17 now). At first I thought that they might just be glands...

I remember when I started moving into adolescence my foreskin started to detach itself from the head to give it the "groove" that exists under the penis head... Now, pretty much right after that happened, I noticed the bumps... I have 3 on one side of my frenum and 2 on the other... They haven't grown since... But I think they might be genital warts.

I have never had sexual contact with anyone... But recently I also noticed tiny little white clusters on my shaft... They might have always been there, I don't know, they're really small, probably about 1/20th to 1/5th of a millimeter, but they are numerous and I'm not sure if they're actually "Bumps;" I think it's because they're so small to tell.

... Also, I have spots similar to the tiny ones on my penis on my upper lips; but even smaller, none is bigger than 1/10th of a mm and when I pass my tongue over them I think I feel like my lips gets a little bit rougher. I just looked really closely into the mirror one day and I noticed...

Anyway what is the likeliness of contracting genital warts from birth?
And how long will they take to go out by themselves. I don't want to have to tell my parents that I might have genital warts. I feel uncomfortable talkign about that kind of stuff with them.
