The actual testicle has body hair, so like any pubic hair it does get an odour if not recently washed. Male genitalia does emit hormones, as does women genitalia. Its like when a male cat can smell a female cat in heat
They don't have a smell.
balls
Guys like girls to smell nice and not sweaty or anything gross just smell nice and us guys will love you
They need washed!
Like Rubber
That is slang for testicles.
yep
A fourteen year old shouldn't even see a guys balls. So, the answer is no
Your scrotum can smell due to many reasons, but the main reason is Bacteria from your sweat.
Hell yes!
this kills sperm cells
Your question assumes guys' balls hurt whenever we are sick, which is definitely false. Any guy you know whose balls hurt them whenever they are sick should be urged to see their doctor!
