How large do the testicles become?

… your balls, that is. You hear plenty about guys’ balls getting heavy when they haven’t cum in awhile… I don’t think I’ve experienced much of this myself. My last orgasm was roughly a month ago and I guess I’m feeling a bit heavier down there, but it might just be my imagination. For those who have gone months without release… do your balls get noticeably fuller? And is there a point where they stop swelling up? I must admit, I’d feel some pride in carrying around golf ball-sized nuts for my wife to see. Curious to hear about your experiences.
