Like everything else with LSD, sex will be wildly intensified and infinitely better than one could have ever imagined. Timothy Leary said it well in his interview with Playboy in 1966. This quote is also from page 127 of his book, The Politics of Ecstasy:
“An enormous amount of energy from every fiber of your body is released under LSD, most especially including sexual energy. There is no question that LSD is the most powerful aphrodisiac ever discovered by man. Sex under LSD becomes miraculously enhanced and intensified. I don’t mean that it simply generates genital energy. It doesn’t automatically produce a longer erection. Rather, it increases your sensitivity a thousand percent. Let me put it this way: Compared with sex under LSD, the way you’ve been making love, no matter how ecstatic the pleasure you think you get from it, is like making love to a department-store-dummy. In sensory and cellular communion with LSD, you may spend a half hour making love with eyeballs, another half hour making love with breath. As you spin through a thousand sensory and cellular organic changes, she does too. Ordinarily, sexual communications involves one’s own chemicals, pressure and interactions of a very localized nature, in what psychologists call the erogenous zones. A vulgar, dirty concept, I think. When you’re making love under LSD, it’s as though every cell in your body is making love with every cell in her body. Your hand doesn’t caress her skin but sinks down into and merges with ancient dynamos of ecstasy within her.”
