The Fifty Shades of Grey Delicious Pleasure Silicone Ben Wa Balls 64g are my first exploration into not only the world of Ben Wa balls, but Kegel exercises as a whole. After having used them for around two weeks every day now, I can happily say they have been the perfect introduction into it, and I couldn’t have picked a better product. Not only have I not gotten bored of them, I can actually feel them working inside me and am able already to monitor my improvements.
