sorry for my last answer, but I felt a little "judged". "feet fetish" is something i've been ashamed for a long time, and it's hard to live with sometimes.
concerning the famous fantasy for straight guys, which seems to shock a lot of people here, I think it's a lot about the attraction for a certain "stereotyped" masculinity (yes, it's a cliché), a lot of gay people are looking for virility, were marked by stereotypes in their youth (the famous macho straight guy inaccessible in high school). The fantasies are not really mastered... it's sometimes beyond us.
(sorry if my english is not perfectly correct)
