I once read in Playboy that if you push real hard on the taint area while having an orgasm that it would redirect your jizz to your bladder, giving you essentially a jizzless orgasm. I tried this once, and it worked. I was amazed. However the second time I tried it, it worked, or so I thought. I had what I thought was a jizzless orgasm, but afterward as I lay there in bed, the jizz came dribbling out of my cock. All over myself. Fuck that. I don't need that messy bullshit.
