I'm kind of embarrassed to talk about this and I am pretty sure some people might find this weird. But really this site is only place I could ever possibly ask this. A few weeks back, one day when I was "taking care of business." I all of a sudden, started sucking my thumb. I have no idea where the urge came from. The same urge has happened almost every time after this. I don't know if it's to make the act seem more innocent like I'm a toddler that doesn't he's doing or what. I definitely don't think it's sexual though.
What do you think?
