Sleeping with a pillow between my thighs

So summer internal clock screw up has finally begun... It's almost 4am. I've been trying to sleep since 1am. I thought I'd try the pillow between my legs because I did that as a kid regularly so maybe my body would shit down quicker? Well it isn't working in that way... 
Does anyone else ever have a pillow between their legs to sleep and then you end up getting horny and humping it?
