is this genital herpes or something else?

I had unprotected sex with a girl about 3 almost 4 months ago. Got tested 4 weeks after and came back negative for everything. Between that time and now every single day ive noticed fluttering (butterfly) feeling in my scrotum and pins and needles feelings in my genital area when im sitting/laying down. I dont have bumps/blisters/itching or lesions nor a rash and wondering what this could be? anxiety on a pin pointed area because I am so freaked out or is this herpes? any feedback would be greatly appreciated! 

I hope not go ask doctor every time and then ask a nother one then another one
