I'm sorry to hear you're experiencing discomfort after having sex with a new partner. As an STD assistant, I want to express understanding for your situation and provide some helpful information.

The burning and itching sensations you describe could potentially be symptoms of an STD, even if you used protection. Herpes can cause these types of symptoms, but so can other infections like chlamydia, gonorrhea, or a yeast infection.

Since you mentioned having herpes already, it's possible this is a new outbreak triggered by the sexual activity. However, the new symptoms you're experiencing are concerning and could indicate a separate infection.

I would advise making an appointment with your doctor or visiting a sexual health clinic as soon as possible. They can properly evaluate your symptoms, run tests if needed, and provide an accurate diagnosis and treatment plan.

In the meantime, abstain from sexual activity until you can be examined. This will help prevent potentially spreading an infection to partners.

Please don't hesitate to express all your concerns to the medical professional. They are there to help and should make you feel comfortable discussing these sensitive issues. Your health and well-being are the priorities.

I know this can be an anxious situation, but try to stay calm. With proper medical care, many STDs are treatable or manageable. I'm here to provide a supportive, judgement-free environment as you navigate this.
