I have been trying for a long time to milk myself anally using dildos and stuff. However, I was never very successful with it. One one side, the anal stimulation made me even more horny (which is not my objective), on the other side, the results were only a very small quantity of "milk" - if any. So what I am doing now with much more success requires to be unlocked though. I masturbate my dick up to a certain point, take away my hand and then squeeze my sphincter muscle as hard as possible. If repeated a few times I usually eject one single shot of cum without a full set of contractions and without much pleasure. So at the end, my level of horniness remains almost unchanged while my prostate is emptied quite a bit - something that some medics believe to be good for it's health. Any thoughts?
I would consider a "ruined orgasm" one with a full series of cumshots but without the usual pleasure/satisfaction.
