I stumbled upon this product while searching on Google and bought it—the hollow version—on a whim. I honestly didn't expect my wife to like it so much. We've been married for 22 years, and sex isn't as exciting for us anymore, especially for my wife, who often seemed to be just going through the motions. But this toy has helped her rediscover pleasure, which I never expected. We used it three times last week, and I feel our relationship has become much closer. This is truly amazing, and I want to thank Xinghaoya. I highly recommend this product to middle-aged and older couples like us; it's definitely worth trying.
