I agree with SiamGuy , and , as someone who has large balls naturally , I would trade them for smaller models ! They are always in the way , and , in this hot weather , they hang way low , and make things like bike riding a hassle , unless you want to wear a jock strap .
Funny , it reminds me of hair issues , when people with straight hair pay for perms , and people with curly hair pay to have it straightened . My nuts are about the size of extra large hens eggs , and I would love them to be small , they would be out of the way , and it would also make by cock look bigger by comparison . Just my two cents worth .
