I have learned not to jack off unless I'm incredibly horny, because that's when the act is most satisfying. But I also get a little down after orgasm ( psychologically as well as physically), knowing that it won't happen again until the horns once again start to appear. I used to do it more often, but eventually lost some of the thrill of the moments before the spurt; it was a bit too ordinary. Now, after waiting, it's heaven. But I can see how someone would get a bit "down" after release.
