I masturbate when im not horny???

i really do like to masturbate, but im not always horny when i do it. I'll honestly want to masturbate when im not horny just to do it because i enjoy it. It feels childish, but does anyone else do the same thing? im not sure. If so, how do you get yourself in the mood to if youre like this? porn only works half of the time for me. Im not sure if this is TMI ...
