I Have A Bump On The Right Side Of The

I have a bump on the right side of the shaft of my penis. It's skin colored and doesn't hurt unless I try to pick it off. This bump makes it uncomfortable to masturbate the "traditional" way. I wanna know what I can do because masturbating the way I have to is a problem. I also get very dry skin on the head of my penis making it uncomfortable to masturbate as well
