My girlfriend has been publicly humiliating me and I couldn't be happier about it.

I 20M have a micropenis, It's on the larger side measuring in at just over 3 inches but it's still notably smaller than most. I've known my girlfriend 22F since elementary school and thus we're very close, closer than I've ever been with a former partner. Because of this closeness I'm much more comfortable telling her about my fetishes than I ever had with my exes. Both of us are fairly kinky and thus we're both willing to go along with the others schemes so when she learned of my fetishes she not only decided to play along with them she also initiates them as well. I'm into a handful of things but most prominently public humiliation especially SPH (small penis humiliation.) She's a bit of a dom so she liked the idea and started embarrassing me in public. At first she would audibly speak about my size in public settings or swat my butt to get me to move but recently she started escalating with the most prominent scenario being when we went to an indoor water park and she gave me a speedo to wear. I thought that was it in terms of humiliation since speedo's don't conceal that much (and they're just plain embarrassing to wear) until we went to a fairly empty area of the park and she pantsed me. With me just being in the water and wearing something fairly constricting it's not shocking that a bit of shrinkage happened at that moment. Needless to say my speedo hid even less than before until we left.
