Well to start with i'm a total newbie with no real experience so i'm sure i have yet to discover a fetish or 2.
One of my fantasies that i completely know that i want to try is for a mistress/master to pick out female clothes for me and teach me to be as pretty and feminine as i can be (makeup, shaving,wigs etc) then have me dress up for him/her and be treated like a pretty girl for the day (at least).

i never thought i'd share that with anyone...i'm glad i did though
