Hi , I had sex with a prostitute about 4 month ago , very drunk , wore a condom but still got myself checked out at the gum clinic about 12 days afterwards . Tests came back negative . However I had a bit testicle ache and also had them checked , now there sending me for an ultrasound because they feel that my testicles feel ok but obviously don t know why I m getting this pain . I also have quite red foreskin at the top of my penis which has sometimes a dull ache , and have recognised alot more veins there aswell .any ideas these symptons could be ?
