Open Question: what are some logical reasons why females may find foot fetishes a bit weird?

[feedcrawler]

i have a foot fetish, from the get-go i let a girl know about it if i'm interested in her. when i go out dating lots of girls find it weird when i ask to rub their feet. lots of em have said no, only a few say yes. why are there only a few chicks out there who are down with it? does it have anything to do with low-self esteem?
