Yeah... what trout said. This afternoon, I took some time off to play with myself a bit. (BTW, been too busy to spend much time here in the forum lately.) I didn't really want to cum, so I got right to the edge, then backed off. At that point, I got about 5 or 6 ooze-spurts of cum (the final quantity was about half my normal amount) without an orgasm. I've never cum this much before without an orgasm (not counting prostate stimulation). Anyway, since there was no orgasm, I had the distinct desire to put all of it into my mouth lol. And since I had cum into my hand, I did just that. So... no lack of desire doing it this way.
I don't know if any studies have been done on this, but my cum tastes totally different when I don't have an orgasm. It's just a bit salty and almost sweet. It actually tasted pretty good! When I cum during a full orgasm, it's extremely bitter (the few times I've tasted it). The kind of bitter that you can't get rid of lol. So with that, there's not only the lack of desire, it tastes awful too.
