wear womens underwear/outfit under normal clothes, go for a walk, with some heels in a bag,
go to a forest or other quiet place, then strip down to ur girls clothes,
put ur heels on and put ur normal clothes in the bag.
Leave the bag with ur clothes in where you are, and walk away.
see how far u dare to walk away from ur bag and closer to busy civilisation before running back
enjoy.
maybe even take some pics/vid to remind urself of the fun
