Ugh, the throbbing ache/tenderness sucks and is very distracting. It's like a migraine in my nuts.
I could easily masturbate to relieve some tension, but I refuse. No need to medicate the pain away since this is due to arousal, not testicular torsion or some other medical condition.
Also, women get an achy vagina with effects similar to blue balls........I've heard it termed as "blue walls" or "blue clit" or "blue lips."
