It doesn't ooze all over the place for hours, like the Mississippi, carrying yeast infections. I was with a woman once who, of her own accord, went down and started licking my penis. I asked her if she would swallow my semen. Stung, I began practicing, and now I can say yes, I would. It is the most elegant way to masturbate.
Nothing is left over.
When I'm with a woman, I do want to splatter on her face. I want to lick it off her face. I want to comb it through her hair. I want her to lick it off my belly. I want her to hold it in her mouth and come up and kiss me.
