You are making yourself feel things that are not there. But getting tested never hurts for gonorrhea and chlymida,
Thank you for the reassurance. I'm still going to get it checked out I think. It's itchy now and there is pain in my stomach and lower pubic area. Half of me thinks it's in my mind. But I'm wondering if there is more to it. There are new spots where they were before now. They are white on the red irritated bit. Sorry to keep going, but I'm worrying myself and it's stopping me functioning properly.
Your symptoms do not indicated a STD, sounds more like a common bruise and irritation from the roughness of the masterbation.
