Testicle problem

recently after masturbation my left testicle feels weird not painful just a weird sensation. have had it checked but still a bit weird. I stopped masturbating for a few days and it went but then i did it and now its come back. should i just stop for a while

The pain is probably not in the testicles but rather in the ducts carrying sperm to the penis which have a muscular coat. This can go into spasm causing pain. As this only happens during or just after ejaculation it is the time when pain usually occurs its not serious

discomfort can linger in the muscle after ejaculation if that makes sense
