Tmj and oral...

Michelle
I have TMJ and it's getting difficult to preform oral on my hubby:( I last maybe a few minutes before it feels like I will either rip his penis off or get lock jaw! Anyone else have this and what do you do to help it?
I massage my jaw and do recommended stretches but it's getting to be annoying:( or any suggestions of how to mimic some moves with my hands while I give my mouth a break? So not creative with this:/
