Is it normal i like to smell and lick another females feet?

I'm a 41 year old woman married with two teenage daughters. I'm bi but don't have sex with other women as much as I'd like to do to the fact I don't have the time because of job and family life. I've been attracted to other girls feet since I was quite young. A friend and I when I was about 8 use to undress after school and play with each other at her house before her mother got home from work. We use to smell one another everywhere and we'd smell each other's feet. I became addicted to that odor from her feet. Whenever I smelled that scent from then on it made me wet and want to be naughty. I enjoy smelling another females pussy and butthole too but I always like starting with feet first because it gets me so wet fast. Are their any other women that like the same? I hope I'm not wierd.
