Best advice i got, is if youve got a regular partner, get them to check your testicles and pecs (breast cancer)every time you have sex, then theyll notice any differences, lumps ,hardness of testicle, etc, if they do straight down the gps, and yes its embarassing to lie on your side and have a chap , or lady, put a gloved finger up your bum, it may hurt it may not, depends on how relaxed you are, but they can tell if youve got an enlarged prostrate, a sign of prostrate cancer,and other problems, been there had it done , and all ok so far, back soon for more tests.
