I have this sort of bump on the side of my penis. It has puss and I did pop it. It is only one and it has came out before. It happens every like 3-5 months or so. It does not itch and it does not hurt. I am confused of what it is. I really hope its not stds. I am a virgin and well... I do masturbate. I need some tips on what this can be. Thank you

Don't be nervous, just go to your doctor, and get him to check it out.
There's probably not much people can do without actually seeing it.
