In today's episode, Tim talks to Max McCullen, a Men's Sexual Health Consultant. They go over the biological side of erectile issues and strategies to address them, including PDE5s (medications like Viagra, Cialis and Levitra), penile injection therapy, vacuum erection devices, vasodilating, pellet therapy, hormone replacement, and surgical penile implants.  Max also talks about the five components of an erection:  visual/tactile, mental, hormonal, nervous system, and blood flow, and he and Tim discuss sex-positive masculinity.
