I'm embarrassed to admit it, but I have a fetish.
Having a fetish isn't embarrassing. Do you want to tell me what it is?
Yeah. I touch myself in the morning when I wake up.
Fetishes are really not that uncommon. Touching yourself is something that isn't bad, so you can continue doing it if you desire.
I feel dirty doing that when I wake up.
I don't think there's any reason to feel dirty about that. You aren't doing anything wrong or hurting anyone, so I think you should be kinder to yourself.
