All I have to say is that this song is about the ONLY time the narrator had sex. Also, I love this song. It is not appropriate to play at weddings (especially since there is a problem with premature ejaculation*, which is not a thing we generally wish on people), but that only enhances my joy when it IS. I go to very few weddings, but I have definitely heard this song at several, and snickered my way around the dance floor each time.
