I'm a 16 year old male & i've only had sex once.

I got a red pimple like bump above my penis & i'm scared it might an STD.

I clean it everytime i take a shower (at least once a day) and it turned into a white head, it's still clearly visible and it has been for a couple of weeks.

I'm scared that it won't go away and that it might be a possible STD.

The only girl i've had sex with was raped when she was younger (14ish) and other than that i was her real 1st.

If anyone can help, please do.

Thank You.
