Hello,if you over masturbate ,it could be the possible cause for pain . Tight undergarments would not cause testicular pain. To know the cause ,stop masturbation for a month or 15 days and see ,if it still pains the you could think of some other cauases. Different size and position of testicles is natural .Since you said its very mild pain ,wait and see .
