Not that I mean to brag but, I have enormous balls, saggy sometimes too if it's warm enough. My balls are so big they deceptively make my cock look smaller. It's a proportion thing. Every girlfriend I've been with has loved my huge balls. The weird thing is I probably wouldn't be choosy about my partners ball size. I like the look of castrated balls and medium or small size balls. I don't like the fact that after castration little if anything cums out upon orgasm. I like to see the juices flow. That being said I'd probably enjoy huge, floppy balls. The idea of my partners balls slapping my taint (or even my balls) during sex sounds like a turn on. I know every girl I've been with says it's a huge turn on feeling my balls slap their ass while I pound away.
