I have these small red and sometimes white bumps on the rim of my penis. I noticed them after i felt a pain while masturbating about 2 weeks ago. I did some research online and it kind of sounds and looks like pearly penile papules but the fact that they showed up after i hurt myself masturbating seems also like it could be some sort of irritation, but theyve been here for 2 weeks so im not sure. please help!

thanks
