I've had fantasies about being covered in cum, having it leak out of every hole. However, every recipe for faux cum that I've found involves eggs or cornstarch or flour which frankly sounds like a yeast infection waiting to happen. If anyone could help me in my search for a homemade fake cum that's safe to put in your body, I'd be much obliged. How about thinning some plain yogurt with water. The bacteria in the yogurt would be good for you. When I saw this post, I remembered seeing a few kinds of lube on amazon that are supposed to be just like cum.
