Too much foreplay.
If you keep fiveplaying him, he'll keep coming too soon!
Foreplay leads up to eventually having sex, however five play often does not. Five play is when a man inserts all 5 of his fingers into a woman's vaginal cavity and then separates each finger from one another. There aren't too many men that could fill such a large hole while having sex. When this is done sexually it is often followed by some form of a humiliating act such as a golden shower, or dirty sanchez. This practice does serve useful when prepping a woman to smuggle large packages of narcotics into other countries.
Last night Jenny and I fooled around, and it turned into five play. I nearly lost my watch, so I left her with a dirty sanchez so she could be as disgusted as I was.
