Desire sometimes ratchets upward soon after hot sex.
Does "the more you scratch, the more you itch" sometimes apply to sexual jollies? Is the reverse true? Intriguingly, the Chinese noticed a "ratcheting up of sexual desire after orgasm" thousands of years ago. Men today do too:
I sometimes feel hornier in the days following orgasm. At such times, I also have strong feelings of attraction for other women (even though I'd never want to have sex with anyone other than my partner).—Tom
My new girlfriend and I got each other off, and now, a day or two later, I'm definitely noticing powerful urges to masturbate and look at porn again (after three months porn-free). It seems so contradictory that our heavy petting would trigger this, but it's happening. I'm masturbating more and I even looked at homemade porn yesterday.
