What Causes Small Growth On Penis And Purple Spot On Urethra?

Hi I am a teenage boy and I am conserened about a couple things with my penis. I have never had sexual contact ecxcept kissing a girl so I don t think I could have an STD but on the bottom of the head of my penis right in between the shaft and glans penis (I am circumsised) there are 4 small growths, 2 of which are bigger than the other 2 and they form a square. They are a whitish red color and there is another one growing bellow those 4. They don t itch or look gross or anything they just bother me because they re there! So what could they be? Could i have genital warts even though I have never even had sexual contact? Also when I open my urethrea there is a purple spot on the left side it s kind of in the middle of the inside of my pee hole and its a little lumpy I guess. Again, it doesn t bother me when I urinate or anything it just concerns me that its there! One time i touched it and it stung! So what could that be?
