I picked up a copy of the 'Cock Coloring Book For Adults-A Hilarious Penis Color for relaxation: Grown-ups Dick Designs filled with Paisley, Henna and Mandala Patterns ... appreciation Bachelorette Party Gifts Idea' (see here) on a whim, and I'm so glad I did! The vibe is fun yet sophisticated - it's pretty much like getting to color your own penis pictures in an adult coloring book! My friends freaked out when I showed them my new purchase - they all started cracking jokes about how this must be what bachelorette party gifts look like these days haha.
In all seriousness though, it's actually quite calming once you get into it – each page features intricate mandalas and paisleys that are incredibly detailed and zen-like. There's also tons of options so if one design isn't your jam there will certainly be another that is more suited to your tastes. All in all, this coloring book surprised me but really left me impressed at its unique ability to make something as strange as penises both stylish and relaxing - definitely give it a try if you're looking for something educational yet totally wild!
