What position is best to sleep in?

Sleeping on the left side with your knees slightly bent and a pillow in between your thighs is the best. Sleeping on your back is also fine.
I tend to sleep on my tummy a lot. I've heard it's bad but I don't find any other position comfortable

 

I almost exclusively sleep on my left side, but that's just me. I can't sleep on my stomach because, you know...things get caught under there. But yeah, other than that I would say sleep in whatever position you're comfortable in. After all, sleep is important and even more important when you're on NoFap.

 

I've always slept on my stomach, it's comfortable .
