Does anyone else have uncontrollable leg spasms during orgasm?

I am a mid-50's male. I developed iron deficiency anemia and subsequent peripheral neuropathy. After what has been around a year of iron supplements my condition has improved. I still have some numbness and tingling in my hands and legs but it is much better. However, I do have one symptom that hasn't improved and I am unable to find any information on potential correlations between neuropathy, leg spasms (with muscle contractions), and orgasm. I apologize for being graphic but I am thinking I may not be alone in this. When I start to reach climax my legs get a mind of their own and I feel a distinct nerve sensation that is not painful but is very intense. I am unable to stop my legs from curling up and it subsides almost immediately after orgasm. It often interferes with or provides such an unwelcome distraction to what should be a pleasurable situation that I would like to know how/if it can be minimized or eliminated. Again, I apologize for being graphic, but this isn't a normal sensation that might occur randomly or to a lesser extent for most of us throughout our lives but something that developed after I knew I was low on iron and really hasn't improved like my other symptoms. I would be curious to know if anyone else experiences this dilemma, male or female, because I could see it being an issue for women as well as men though obviously, I can only speak for myself. Does anyone else share my situation or know where I can look for relevant information? Thanks.
