Ok well to start I've had it for about 4 months but it was rather small and shiny I look at my penis today and it transformed into a small little shiny pimple looking thing to a huge swollen bump I mean its 5 cm in diameter and about 3 cm tall its on the lower right hand side of my penis about an inch from my sac I tried to pop it and a verrrrryyyy tiny of zit puss came out but I don't think it's a zit as of now its has a shiny spot and is VERY swollen
OK so I'm 16 I'm pretty sure its not a std :p
Or a zit
