Help plz !!!! Does this happen to anyone else???

Keri • I'm new to this. Where do I start? I'm married. I may be weird but I love who I am.
When I orgasm I start to twitch I don't know what it is? Or why? I don't even know if I cum. I can't squirt and nothing comes out just wet. I can feel my muscles contracting. Does any one have this problem or any advice how to stop the twitching?
