The evolutionary selection aspect is curious. Is "natural" always "better"? Facial masculinity is correlated with higher testosterone production in response to competition [1]. Higher testosterone levels are also correlated with aggression and violence [2]. Could birth control steer evolution towards a less aggressive, less violent society? Is that a bad thing? You argue that choosing the "wrong" mate could be an issue -- is a less-violent partner the "wrong" choice?
