Warts in my penis ???

i.m from spain.i don.t speak english fluently. i saw a small bump in my penis four days ago. could an expert tell me what this is. i will go to the dermatologist in two weeks but i am really afraid. thank

you can see sand because I have just came back from beach.

Yes, I see the sand in the photo.
It could be a normal bodily wart, rather than a specific genital wart - go see the dermatologist to be sure
