Sex with a new partner

Sex with new partner
I had unprotected sex with a new girlfriend.
She works in a Doctor's surgery therefore she is regularly tested for STI's.

Three days after sex i had penile tingles and itches with no discharge.

I penile swab taken for herpes but it was negative. I have also had severe muscle aches and weakness.

The penile itch has gone and the muscle aches have subsided drastically almost two weeks later.

I still feel maybe i have an STI.
The test results for chlamdyia and others are negative.

I have seen my DR who thinks it is just a viral infection that will clear up.

I still have to wait a few weeks before I take an HIV test.
