Got no idea on why they do so, but my balls behave very similar. I think it's a PFS thing indeed, they didn't before. They've also certainly gotten smaller and harder I think. I do take blood tests on and off to see where I'm at, and testosterone is in range though, so they still "work" that way.

I think CD once said (correct me if I'm wrong) his balls still hang low sometimes and he and his gf sometimes lol at that. Also don't ask me why I remember that...

Happy 4th of July from the UK!
