ive just been checking my testes as every man should do on a daily basis to check for lumos etc.i saw on a tv programme that many men dont do this and are there fore putting their health at risk by failing to check up on themselves.so im wondering how many men here check theirs testes and how often?do you do it yourself or get your partner to help or assist you? i did make quite a frightening discovery when i tested mine regards the size difference between right and left testicle. on the one hand my right testicle is the size of a tennis ball. but the left one is a great huge thing. : - )
