I m a white male, 36. My scrotum has always been VERY tight to the point that my testes are inside me 80% of the time. I don t have a lot of hair growth overall, even though my father is hairy. I ve never had a low voice, but i m not gay. My testo levels seem low I think at 136. I m very sexually active and have muscle, yet it s very difficult to maintain. My Right testicle in particular has an ache toward the back near anus where I feel a lump. I think that s Vas deferens. No doctors have said there is a problem, but how can they know if they can t feel the testicle? Based on my descriptions, I d appreciate some insight. Thanks!
