Review on Organic Peppermint Pure-Castile Bar Soap by Dr. Bronner’s - 5 oz (6-Pack) - Gentle and Moisturizing for Face, Body, and Hair - Biodegradable, Vegan, Cruelty-Free, Non-GMO by Katie Moore

If you like lots and lots of foam, a minty smell and spotless cleanliness. Look no further, this is the soap for you! Expensive, but lasts a long time and does not wear out. If you are female, do not use this on vagina or buttock crease as it will burn you. I use a different soap for this area and it works great (worth it). I don't know how it will react to the penis but I don't see a problem as it is encased and not exposed. Try this product, you won't be disappointed!
