How Can Foreskin Lumps With Discharge Odor Be Treated?

Hi, I'm 15, I've never had sex, but I do regularly masturbate, I recently noticed strange 'bumps' around the top of my foreskin, (I have no idea how long it's been there), and about once a month, I produce what seems like pre-cum, but with a White, smelly discharge. Also, once fully erect, I can't pull my foreskin back to the base of my penis head. Can you offer any solutions? Please, I'm quite scared, if I had sex, would I pass this to a girl?
