It's great that you've taken steps to get tested and confirmed negative for several STIs. However, it's essential to understand that genital herpes (HSV) can sometimes be asymptomatic or show symptoms sporadically. The tingling and pins-and-needles sensation you're experiencing could potentially be related to HSV.

If your cystoscopy results confirm no infection but the symptoms persist, it might be a good idea to consult with a healthcare provider who specializes in sexual health or infectious diseases. They can help determine the cause of these sensations and provide appropriate guidance on whether it is safe for you to have sex again.

Remember, accurate diagnosis by medical professionals is crucial when dealing with such issues. Take care of yourself!
