I got an epilator recently. I'm such an irredeemable tranny. The pain is indescribable. I tried doing a big patch on my leg so I'll see how long it stays like that. Apparently it's a whole week until the hair starts growing back. I'm thinking of getting drunk next time so it doesn't hurt as much.
In terms of using the epilator on my face it might be easier than anywhere else because I have suffered from trichotillomania for a long time, meaning I'm used to ripping my facial hair.
