Episode 431: How Men Can Build Sexual Confidence
A lot of people think that sex is just easy for men. But it’s not. A heck of a lot of guys are walking around with sexual anxiety and are worried about their body and/or performance. This can eat away at men’s confidence, leading them to avoid sex, or to have sex that’s less than pleasurable. In today’s show, we’re going to talk about how to build confidence in the bedroom and bust some common myths about male sexuality.
I’m joined once again by Dr. Joshua Gonzalez, a board-certified urologist who is fellowship-trained in Sexual Medicine. He is a Sexual Health Advisor to Astroglide Lubricants, and one of the co-founders of the sexual wellness brand Popstar, which creates science-backed products to support male sexual health and pleasure.
Some of the specific topics we explore include:
What does it really men to be “sexually confident?”
How do popular myths about male sexuality inhibit men’s confidence in the bedroom?
Is more testosterone really the key to more confidence?
What can men do if they want to increase their sexual stamina?
When should you see a professional about sexual performance concerns?

Episode 426: Why Sex Ed Sucks (And Always Has)
Sex education is highly controversial. Last year alone, 27 US states introduced bills aimed at restricting sex ed! However, this fight over what sex ed should cover (and whether it should even be taught at all) is nothing new. We’ve been having the same fights about sex ed for over a century, and that’s a big part of the reason why modern sex education still sucks.
I’m joined today by Margaret Grace Myers, a writer, researcher, educator, and former bookseller based in Maine. She is the author of the new book The Fight For Sex Ed: The Century Long Battle Between Truth and Doctrine.
Some of the specific topics we explore include:
Why do we keep having the same arguments about sex ed?
What really holding sex education back?
How did abstinence become such a dominant part of sex education in the US?
Does abstinence education actually work as intended?
Why is it so hard to access comprehensive sex education when it’s what most parents say they want?
You can check out Margaret’s website to learn more about her work.

Episode 425: What Determines Our Sexual Orientation?
Why are some people straight while others are gay or bisexual? What determines our sexual orientation anyway? Today, we’re going to be diving into what we’ve learned about the biological origins of our sexuality from decades of scientific research. As you’ll see, there’s not a simple and easy story—it doesn’t boil down to something like a “gay gene.” It’s way more complex than that!
I am joined once again by Nathan Lents, a Professor of Biology at John Jay College, where he is the director of the Cell and Molecular Biology program. His research lab studies human genetic evolution and forensic DNA technology. He also writes popular science articles and is the author of the new book The Sexual Evolution: How 500 Millions Years of Sex, Gender, and Mating Shape Modern Relationships.
Some of the specific topics we explore include:
Is same-sex attraction genetic?
How can two people who share 100% of the same DNA have different sexual orientations?
When researchers are studying sexual orientation, should they be looking at attraction, identity, behavior, or all of the above?
Why is having more older brothers linked to greater odds of homosexuality in men?
What other biological factors are associated with sexual orientation?
You can check out Nathan’s website to learn more about his work.
