The other day, during masturbation, I felt a small zit sized lump under the foreskin of my penis on the right hand side of the glans. Also on the head of the glans is a limescale like substance, which can be removed with wet tissue paper. Now during masturbation, the little zit sized lump hurts, but it only hurts when i apply pressure to the area. Also today, I have noticed an additonal lump slightly smaller, also on the right hand side however a little lower down.
PLEASE help me, I dont know what it is and I am too scared to ask my parents to go to the doctor.
