I've taken a few years worth of my wifes birth control pills on and off, I know I'm new here but...
We've been a cuck couple for about 6 years now.
They did lower libido quite a bit, they also shrank my dick and balls, I was around 6 inches when I started taking them, I'm down to 4.5 now, and very small cumshots. They did round out my figure a bit and I did grow a small set of tits from it, they're not pecs anymore, they're definitely tits.
So yeah, thats the gist of it. If anyone has any questions, feel free to ask. I'm an open book.
