Almost every woman I have ever dated has told me that they hate the pill and believe it seriously fucks with their head. I've never encouraged anyone to use that method, and I wish we had better male options.
Same here. And every women I know who stopped taking the pill would rave on how good it made them feel in general, and specific things like an increased sex drive. I was there when my current GF stopped taking the pill and can attest to that: an improvement on many fronts and seemingly no disadvantages. But yeah, billion dollar industry, people are used to it, convenient, ... so I don't see this getting better soon.
I had a girlfriend get pretty severely depressed upon starting birth control (and it cleared up shortly after going off) and traveled with a girl in Bolivia who had to give herself shots a few times a day because she had gotten deep vein thrombosis on her flight, susceptibility to which is apparently a side effect of her birth control. It really is insane how much it affects the user's health.
Every similar male options has, sadly, been far, far worse. I'd love a pill to render me temporarily sterile. Sadly the required chemistry seems to be... suicidal for men.
