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?

Is kink just about whips and chains? Is it always about sex? Is everyone who’s into kink working through some type of trauma? In today's show, we're diving into the science of BDSM and debunking common myths about it. We’ll unpack what kink really looks like in practice, how consent and trust are at its core, and what it is that really draws people to BDSM in the first place.

  • What might people get out of BDSM besides (or in addition to) sexual fulfillment?
  • How do people typically find their way into BDSM?

Episode 427: How We Can Make Sex Education Better

The sex education we have in the United States today isn’t really working. And, unfortunately, it's only set to get worse as a growing number of states are pushing to restrict what students can learn in these classes. So in today’s show, we’re going to talk about why it has been so difficult to make sex ed better and what we can actually do to change it. I’m joined once again 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:
  • How many US states today require that students receive sex education?
  • Why don't we have a federal mandate for sex ed in the US?
  • What can we do to improve sex ed in our own communities?
  • What can we learn from other countries that are getting sex ed right?
  • Why do we need to stop thinking about sex education as a one-time talk or course?
You can check out Margaret's website to learn more about her book. Got a sex question?
