This is a good article that could spark hot debates. I totally agree with you that the majority of contraceptives have focused on females and little on males, hence these supposed non-hormonal contraceptives for males is a welcomed development. I just wished research can also intensify towards developing non-hormonal contraceptives for females as well.

Interestingly, while contraceptives have only focused on females, creating sexual satisfaction during the act has mostly focused on males. I have seen zillions (permit my hyperbole) of penis enlargement drugs and very little of vagina tightening substances. THis is another area of debate as most male organ enlargement drugs (really dont know how effective they are) tend to have their own side effects as well.
