(NEW YORK) — Human sexuality is as varied as the features on our faces.
Annie purportedly has the largest breasts in the world — size 102ZZZ. Cristian was born with a condition called gynecomastia, which is an overgrowth of breast tissue, causing his chest to grow to a B-cup breast size.
This month, Discovery Fit & Health airs Sextember, highlighting its most intriguing stories about those with odd physical characteristics and erotic yearnings.
The series, which airs Sunday at 9 ET, takes a look at sex, love and intimacy.
“I think the greatest thing about Sextember is that it allows a dialogue,” said Ty Tashiro, a psychologist and researcher in sexual health from the University of Maryland and a consultant for Discovery. “It lets us know there is diversity in the way we are built and the things we want and how we function.”
Trent, in the episode, “The Inseminator,” has been running a one-man sperm bank out of his living room for the past six years. In high school, he took a vow of celibacy in order to donate his body to scientific pursuits.
So today, he helps childless couples get pregnant, protecting his sperm so it is optimal for fertilization. Trent is still a virgin, but with 15 children.
Josh and Jasmine flip homes for a living. But what happens when they show their own house, which is filled with sex furniture?
Other episodes include: “Dominatrix in Training,” when Megan decides to reveal her kinky side; and actress Maggie Gyllenhaal hosts “Why Is Sex Fun.”
Sleep orgasms and sleep sex are also slated for Sextember.
“People have different ways of gratifying themselves and enriching their lives,” Tashiro said. “Having tolerance for diversity is a good thing.”
The recent popularity of the erotic book, Fifty Shades of Grey, illustrates a more open attitude toward what was once considered kinky sex.
Those who actually engage in sado-masochistic behavior are a “substantial minority,” according to Tashiro, who has been a consultant on the Sextember series.
“In the U.S., we tend to culturally talk less openly about sexual activity, especially when it falls outside the normal range of sexual behavior,” he said.
Those who are different, “tend to keep it to themselves,” he said. But when researchers ask anonymously, “there really is a great range.”
