For example, Comfort calls out bisexuality
as a problem that unravels foundational relationships and ruins sex. As a bisexual reader, it was upsetting to read that "women can sleep with women for sexual pleasure but they shouldn’t leave their male partner for them" and "women exciting each other is a turn on for males". Throughout the guide there’s a very clear disregard for marginalised and disenfranchised people, and although The Joy of Sex
is noted for progression by including information about women, Comfort never speaks directly to us, only about us in disturbing ways. It’s obvious that when Comfort penned this book, he was addressing slim, straight, white, able-bodied and monogamous couples only.
