Seeing as I've recently been diagnosed with herpes, I'm rather displeased with the responses from the other posters, claiming "not to worry" or immediately chastising you for not using protection. (I didn't read anywhere that said you didn't use protection.) Furthermore, many STDs can be contracted even WITH a condom. Factually a condom doesn't always cover all areas that could be effected by the onset of a herpes outbreak. Additionally, 70% of people who contracted herpes did when there were no actual signs of an outbreak. I don't agree that you shouldn't worry. Any time something doesn't feel "right", you should worry about it. If not only for the benefit of your own health, but because you ARE sexually active and may be putting your partner at risk.
True, the only way you will really know what the issue is would be to see a doctor. If it becomes REALLY uncomfortable, take a quick trip to the Urgent Care - they've got all they need there to properly diagnose you, and you don't have to wait the typical 2-3 weeks for your gynocologist to see you.
Things to look for:
- Have you recently shaved "down there"? If so, it could be razor burn, ingrown hair or a pimple.
- Have you ever had similiar symptoms? Maybe in other areas? If so, it's possible you are in stage 1 of genital herpes. Stage 2 will be WAY more unpleasant! (A full outbreak consisting of several "pimple like" gatherings, which turn to blisters and hurt beyond imagine!) This is why it's important to get it properly diagnosed. There are preventative meds that can reduce the risk of further outbreaks.
- How 'sexually active' were you and/or your partner prior to your relationship? The higher the number of your sexual partners, the greater the risk that you've contracted an STD.
Don't sit around and wait if the problem persists. If you think it's a pimple, put some peroxide on it. That should dry it out within 24 hours. If that doesn't work - see someone IMMEDIATELY before you further jeopardize your health, and possibly the health of your partner.
