im 16, i have had unprotexted sex once. but this wuz like during the summer. there are maybe 6 bumps on my testies and there seems to be more popping up becasue there was one then more now. they itch a little but i think its from sweating. they look like they want to be popped like a pimple. white stuff kind of comes out. is it from shaving or do i have to worry about something.
