Okay so I found a bump on my scrotum the other night if I dont mess with it the bump is like a off white color and hard to the touch it looks like it has pus in it but I tried to pop it with a needle and all it did was bleed. Im really worried but the only off putting thing is ive been single for over a year and I havent had intercourse in months. So is it just a pimple? Or should I be worried? Thanks in advance.
