Friends, fans, families, fugitives, those with no girlfriends since birth, “DOMs” and yayas are invited to the launch of  RJ Ledesma’s newest humor book, “Playing with Pink Parts: RJ Ledesma’s Guide to Gayumas, Aphrodisiacs and Love Spells,” on Sept. 20, 6 p.m., at National Bookstore Glorietta 1, Makati.

“The book has something for everyone with pink parts,” Ledesma said. He convinced a magician to share some modern-day love spells using text messaging, e-mails and Twitter; interviewed mystics on how to concoct a homemade gayuma; and consulted a naturopathic physician on the ideal combination of herbs to create a potent aphrodisiac. He even visited a urologist (but managed to keep his underpants on) to ask about what were the most effective aphrodisiacs available in the market.

Ledesma is the author of “Is it Hot in Here or Is It Just Me: RJ’s Guide to Flirting, Body Language & Pick-Up Artists,” and “It Only Hurts When I Pee: RJ’s Guide to Bodily Gases, Hair Loss & Pink Parts,” both finalists in the National Book Awards.

“Playing with Pink Parts” is available at the humor section of National Bookstore, Powerbooks and Bestsellers nationwide.
