I've Had Close To What Looks Like A Hundred Ingrown

I've had close to what looks like a hundred ingrown hairs mysteriously come up on my penis Over the past two days all that I have done different is have sex with a really tight girl and I have a pretty big penis first I thought you shave in my hair that was growing up my penis would solve the problem but after I shaved it went bezerk I have a picture if you need one
