abnormal growth?

[Mulengro]

i paired up my two boars yesterday, and since doing so i've noticed that my older boar's testicles have swelled. i thought that i might have been just seeing things, as it were, but my girlfriend mentioned (through some embarrassment) that she'd noticed the same thing. is this normal? what could be causing it? he's not really humping the new little guy, just doing the mating strut and typical grunts and "machine gunning". any help is appreciated! thanks!

I think he's probably just excited. My older male shall we say "protruded" a lot when we first got his cagemate. It lasted off and on for about a week.
