Sometimes i orgasm in my sleep and i feel really guilty because my partner hates it as i would but i can't help it. Sometimes it wakes me up and sometimes he has noticed me thrusting aswell. We have sex a couple of times a week but if it gets to a few days and we haven't, I am worried that it will happen in my sleep instead. Sometimes it happens even when we've had sex the day before. I either dream i am mastrubating of having sex with him. What can i do to prevent it?
