My wife and I used the pull out method for 4 years with complete success. We have since had a child, however only once we had many long conversations about the subject and had, together, decided to do so. But you are absolutely correct in that you have to know your body and know when you need to pull out. It got to the point where even she knew when that point was.
sure, give me your number
Your wife is sexy, slutty, and a cheater. What more could u ask for
