My husband does not like sex and has not been interested in it for years. He now complains of pain in his left testicle. He does not like to become sexually eroused and therefore never has the need to ejaculate. Can the lack of ejaculation cause pain un the testicles

Maybe another approach why doesn't he like sex?talk to him.If he has constant pain he should go see a doctor.

He should not be having pain for this, He needs to see a doctor if he is having the pain
