Hello! I have some questions about my well-being. Around 4 days ago, i went to go get tested for HIV because i was very concerned. Luckily, i came out negative but im still worrying nonetheless. Ive had 2 different sex partners in the past month and 1 few days after getting tested. Im still stressing this. Ive been having stomach aches lately, maybe since 2-3 days ago. They re not very bad aches, just those aches that will occur, then leave again, but sometimes i would go to the bathroom. Then i finished showering lately, and i found this dark-purple looking spot on the side of my penis head, it looks like something similar to a bruise, and i got very nervous & worried. My health anxiety became worst at this point. What could all this be? Im very nervous and i cant stop thinking about it! Help me! Thanks!
