In my opinion, the best choice is to buy a toy from a sex-shop. Because homemade are not safe, they can break and get stuck inside of you. There are a lot of people in the worldwho faced serious problems because of these homemade experiments. If you don't have a lot of money, take a look on Edenfantasys, they have good discounts on a lot of products, and that products are safe and qualitative (I've bought one vibrator from there and I'm really happy with it)
