As for me, a female, from my point of view, I quite enjoy feeling my bfs balls slapping against my ass/cunt, I don't know why, teehee.
HUGE balls man here. Call me crazy, but very often I look at ballsacs before I look at cock. Just something about those two boys that is a huge turn-on. Maybe it's the load lover in me also, equating a large set of balls with a bigger wad--though this isn't necessarily true. For example, my balls are average, but, after comparing with numerous men over years of dating, I know I have larger than average loads. And my partner's balls are bigger than mine, but not enough to explain his loads that are about 1/5 the mount of mine. Also, I've been with bull-hung guys who came in dribbles, routinely.
As for Nouveau's comment, I cumpletely agree that the sensation of of feeling a big sac slap against my ass is a fantastic feeling. Physically, it isn't that big of a deal, if you thin about. I think the issue is more psychological: when my partner's balls are slapping against my ass while we're fucking, it can only mean that he's entirely committed to the fuck and i've been able to take in him all in (which can be a challenge at times).
Finally, i gotta say that shaved balls are awesome. I've seen several guys, gay and straight, without shaved balls who looked good. But if you're going to pay serious attention to a guys balls, a nice shaved set is typically easier to work with. This applies whether their in your hand, or slapping against your ass or chin.
Oh, and as for correlation, i've never been able to find one. But, from an assthetic perspective, proportion is best. The most beautiful cock and balls i've ever seen/had were from a guy from Missouri. His cock was large in ever respective, he had a tremendous shaved ballsac, and they both worked perfectly together from visual and sexual standpoints. His equipment looked like a big, perfect dildo. His load size was proportionate, however. Gusher.
