ELI5: Why is the shower curtain following me and trying to stick to me while I'm showering?
gpt
The hot air created by the hot water pouring into the shower area rises and creates a little vacuum within the shower.  This causes the air-pressure on the outside of the curtain to be greater on the inside so it "blows" the curtain in towards you.

Alternatively, this is because YOU are so hot that the air heats up and rises resulting in the same affect, but double so because the curtain can't resist your sexiness.

Probably the later of these...
