Shunga is high quality by using the best ingredients and no two products are ever alike. Shunga really knows what it is doing. I would start with their all organic set The Garden of Edo. That set would be an amazing introduction to Shunga as well as be the foundation to all love making (foreplay, oral, intercourse, baths, bondage, ect). Not just in the set, but all of their products can be used together. There is never any stickiness, staining, or bad tastes. There is only eroticism, fun, and passion. Shunga is an improved version on Kama Sutra.
