A sexual session involving only the Missionary
position. A "Hole" of Missionary Golf refers to one time having sex, and as such, playing a full 18 holes of Missionary Golf is quite likely impossible.
It resembles golf in that the "Holes" are slightly different, some longer, some shorter, some times you use brute force, sometimes you have to use finesse, but they are all basically the same. I believe there is a certain beauty in playing Missionary Golf well.
