im plan to start Penis Enlargementing soon but this question im going to ask is not to do with Penis Enlargementing. its strange but i have noticed that the colour of my semen is sort of a yellow instead of white. it wasnt that way before, i have noticed this for 5 or 6 months now. i can't understand why tho and its bugging me alot. i did use to jerk off alot but not so much this last year or so just like a few times a week max now. is something wrong with me, im mean im worried that i might be infertile or something i dunno. im only 21 years old any help?
