that really sucks, im sorry to hear it
that being said its not terminal, and as massive as it seems today (and it is massive) itll be something youre going to get over and get used to. its not going to bother you in a few months or whatever.
i know several people who have had the same thing, or testicles removed for one reason or other - 2 guys in motorbike accidents etc, so really, theres heaps of peopel out there that have the same outcome so try not to feel alone
the guy who got a stainless steel replacement testicle is a cunny funt. he sets off airport metal detectors then proudly pulls out his balls lol
