It would be awesome if this could be part of a men's liberation movement, like how women were liberated in the 60s when the pill became available.
Was it the pill that led to women's liberation? Or was it penicillin? The pill allows women to have sex without getting pregnant. Penicillin allowed people to have sex without getting diseases. AIDS has somewhat rolled that back.
Before HIV, there was still always Herpes, Hepatitis, HPV.... e.g. anything viral. People were just more ignorant of STDs 50 years ago, but that doesn't meant they still weren't getting them. You're still going to want a condom on the first date no matter how many new types of contraception get invented.
