Why do woman suck mens ball?

It probably has a lot to do with the human constitution & how both males & females are made. Men are muscular with strongly built sinews, tendons & muscles whereas women are weak, limp, frail & have more brittle bones. This explains why they are more prone to osteoporosis, bone density & composition diseases post menopause!

Now, there's no scientific evidence that all men like to have their balls tickled, sucked, caressed or fondled but probably there exist a lot of erogenous, sensitive & pleasure spots in those areas & nerves that get stimulated during sex thereby giving. Another thing is that women by applying pressure on the balls release a lot of sperm into the Vas Deferens which bring about male orgasm faster. The concept of a huge/gigantic load is not an aberration, its very much a fact
