Left testicle pain. There and in groin.

Ok so I had my first unprotected sex 2 years ago. I have anxiety since then. After that day, I wasn't feeling well. I was so stressed that I was feeling I had caught STD or even HIV. I was stressed for months. Feeling tired and not talking to people. Like it's end for me. I was more worried. After 6 months, I had my test. Negative. But then i had a feeling what if I have Chlamydia or gonorrhoea. I checked symptoms. I found epididymitis. I checked my testicles. Right one seemed one ok. Left one had a certain point which pains a little when touched. I kept touching and pressing to check so much. The pain radiated to my inner thigh and groin. I was scared. But after days or weeks..It got better on its own. It doesn't pain on its own. But only when certain point is pressed. Just below front or back of left testicle. I didn't bother to touch and check that point anymore since then. But today I checked it again too much. When I press my finger on it I feel pain a little there and in groin.
