I. The best type of orgasm (types I and II were lumped together and described as “good sex” orgasms). This one ranked high on both pleasure and physical sensation, with lots of throbbing and euphora.

II. This was the other type of “good sex” orgasm, which ranked very high on pleasure, but lower on physical sensation.

III. The third and the fourth types were classified as “not so good sex” orgasms, I guess because they were too polite to say “bad sex”. This was classified as medium pleasure, but low physical sensation.

IV. The lowest of the low, this one was low pleasure and sensation. Generally not great.
