I am so happy I found this because nowhere else online am I finding reference to this. Female, mid-forties and I have lower leg spasms right before orgasm. It’s so distracting that, if it happens, I can’t climax (trust me, I’ve tried). It seems less likely if I wear socks, but that’s not full proof. Not sure about iron levels or whatever—always figure I cook on cast iron so I’m cool on that front. This problem is really annoying. Affects me probably 50% of the time. Not even sure what doctor to ask about this (my reg physician was like “not my problem”).
