I have used these products for over 20 years. You will not get the same results with one product, but over the long run, you will be happy with what you buy. Here are my top recommendations. (Note, that the ones that are not listed are good for beginners).
The first thing you want to try is an actual penis enlargement procedure. These procedures are only available in Japan and they are not very popular with the rest of the world. In the US, it is easy to get a penis enlargement procedure done, so the main reason you are interested in penis enlargement is because it can be done cheaper. But in Japan, the procedure is much more difficult and you need to be extremely careful and patient. So I recommend the following companies that can provide penis enlargement procedures, but only for women. The second thing you need to consider is the price for the penis enlargement procedure. In Japan, a normal man will pay around $400 for an enlargement, but a female can get an enlargement done for less than $100. This is because the company is not allowed to charge more than $100 and you don't need to get a referral.
