Hi,
I'm pretty sure it is a theraputic kind of a thing more than something that's compulsive. It relaxes me, the hot water helps to relieve the tension my back muscles and the steam from the shower soothes my sinuses. I guess it's like a mini spa break and I like taking a lot of them.
Thank you for your input. It doesn't seem so whacky to me anymore.
Myself, your taking a bath with a bathing suit on made me laugh.
