how to avoid fucking your bed in your sleep?

so, i’m pretty edged up at the moment. leaky cock, pre cum everywhere, full achy balls, desperate as fuck…you guys know how it goes.

naturally, i don’t want to cum. i can’t sleep much when i’m like this, but i try to. and when i do, i always try to sleep with my belly up, so accidents are less likely to happen in my sleep. but when i wake up, frequently i’m with my belly down, fucking my bed in my sleep. today, i was taking a quick nap in the afternoon and i woke up fucking my bed ALMOST cumming. it was really close, by some miracle i woke up just in time. i immediately turned around and held it in. that has to stop, or else i’ll cum, and i don’t know how to control it, i can never feel myself turning around in my sleep. anyone has gone through something similar and has any advice for me?
