human
Hey I got a weird bumb on the shaft of my penis and it's rather hard and swells up after masterbation it's got a little white on the to of it and it's not a std cause I'm still a virgin and when I touch it it doesn't hurt but it's real tender I guess I can say or like a little pinch but I would like if I could get a answer from this because I'm a little embarrassed to go to a doctor lol

Itis most probably a wart.  Itshould be seen by your family phisician. If cofirm itcan be removed surgicaly. Itcan alsobe veneriall wart. Inthat case a VDRL test istobedone. If positive  penicilin injection will cure it.This site is not for venerial wart.  They generaly present in glans penis. Decide accordingly.
