OK, a few days ago I noticed a small red bubble on the front of my penis (smaller than a pea) and I'm extremely worried about what it could be... I'm 14 years old, I rarely masturbate, I'm quite obviously a virgin, and it just appeared a few days ago. What could it be? (Honestly I know this is a bit disgusting but I shower around once a week as I don't sweat much.)
Thanks.
