Want to get the most out of your pecker. Take some Maca once in a while. Just a pill the night or morning or just before you get some. Only once in a while, not every day or every other day. Your cock will get so rock hard and swell like crazy if you're rested and hydrated. I don't have any size problems, but when I take maca my gf (ex now) would just be beside herself in how hard I stayed and how big I felt.
