Orgasm Seizure 👀

Hey Gals 💕, 
Basically I seem to have this thing where every time I orgasm I have these body seizures 👀 I can't quite think how to describe it but all my muscles across my whole body start to cramp up and my joints start hurting. Bearing in mind I'm still a virgin, so I've only ever experienced this when getting my 3rd base on 👅 however I imagine it would probably be the same reaction during sex. The problem with it is that it hurts a fair amount and I generally have to get the guy to stop if I feel myself climaxing which is a bit of a mood killer for the both of us tbh. 
Anyways I'm just wondering if anyone else has had any similar experiences with this or know of anyone that has? 
Much love girlies 😘Â
