Ron,
Perhaps you just need a different toy to play with. Try a rubber dildo with a chopstick forced up the center to make it stiff. Then go hunting for the right spot and try more pressure. When
semen begins to flow out spontaneously, you know you're not too far from the mark.
You can also just skip this messy approach and massage it through your
perineum. Try to masturbate until
orgasm while rubbing this spot. Stop just before orgasm and rub the spot harder. The first time I did it, I got myself to come by rubbing that spot after I had masturbated just short of orgasm. You should be able to produce a warm, pleasant, tingling sensation in this region which will enhance your orgasm. This works better if you haven't masturbated for a day or two, so you have a "full tank."
Happy hunting.
