I am a male who had unprotected vaginal sex with a woman 6 months ago. I was protected initially, then for about 30 minutes, it was unprotected. I have researched with vigor so I'm a bit uneasy. My symptom, I would estimate about maybe 3 weeks after the encounter I noticed two "white lines" on inside of my cheeks. Looks like maybe an ulcer on one side, but it doesn't hurt at all. I have bitten the inside of my cheeks a couple times as well, but the "marks" on inside of my cheek have not gone away. I've never had this issue before. I've also had a couple non-painful bubble type bumps inside my lower lip. I have also bitten my lower lip a couple times, not sure if it relates. I got tested for all STDs, except Syphilis and HIV, negative on that front. Lastly, on the foreskin of my penis shaft (" underneath"), Ive noticed a flesh colored " bump"..on a vein, its not raised or hardened, but does have an "indent", part in the middle. It's very tiny, the only way I seen it was when I inspecting my penis..and pulled my shaft back and seen it. I've read this site and other sites about anxiety. I will get tested, but I wanted some insight first. Ps, I have not had any other primary symptoms..such as headaches, fever, rashes, etc. Thanks in advance for your review!
