About 5-6 days ago I had sex with someone who likely has had many partners. I wore a trojan extended pleasure condom, I asked her if she had an std she said no (yes I know she could have lied or been unaware of having one), and lastly from my perspective (which is not a doctors perspective obviously) I did not see anything in her vaginal region that alarmed me as to her having some kind of infection. During our sexual encounter we had vaginal sex and she also put her mouth on my scrotum. In the following days in my groin area, inner upper thighs, scrotum and penis (places covered and uncovered by the condom) became SLIGHTLY itchy. Not itchy to the point of oh my gosh I have to scratch but just that it was slightly present. I'm not sure if I really have a TRUE itchy area as symptoms have been described or I'm just freaking out and it's all in my head. My scrotum at times is red as well. A fews days before this sexually encounter a started using a new bodywash so this may have an affect on it, and about a week or so before that I trimmed myself down there, but not down to the skin. I have not noticed any blisters or anything... yet. I am greatly regretting this encounter because I know she has had countless partners. I will be getting a test done in a week, but for right now any thoughts on what the issue probably is. I know from research I see that most people receive mild to no symptoms from herpes and a lot of people have herpes so that scares me. But why would a spot covered by the condom itch? Also I went about a year ago to get my penis examined because I thought I had herpes and the doctor said no, that the two small bumps on the head of my penis (that were there for a while) was a reaction to the condom and not herpes. But knowing all I have shared can I have an honest belief as to what I may have? Is it herpes, an STD, something else, all in my mind? Giving percentages if possible. Thanks!
