Many men would LOVE a reliable, non-condom, male-controlled birth control method

Currently for men there are two options

condoms, which are problematic and difficult in several ways, or vasectomy, which is essentially permanent or at least difficult and uncertain to be reversed.

The third method is to take WAY too many TOO HOT baths, but that also has uncertainty and is a real hassle.

As it stands, really for men they either need to use a condom, or trust that your female partner is reliable.
