That's how I finally did it.
There's another way you could try, or get your partner to help you with.
Start off slow. Let your orgasm land on your stomach/chest, and at first don't even think about tasting it (you shouldn't at this stage anyways, the almost involuntary reflex against it should kick in). This time, just take a finger and move some it around on your chest. Touch your fingers together. Just study it. Then clean it up. Do this a few times, until the sight of expended semen holds no sort of taboo for you now.
Next, try taking one droplet of it after orgasm and dropping it into a full glass of soda. Then stir and drink. One droplet, you shouldn't even remotely taste it. Do this, but each time add just a little bit more semen or have a little less soda in the glass. Do this until your adding a full "fingerful" of it.
Next, try doing this same thing, but with water. Start off with a droplet and progress to a fingerful.
After that, try the same thing with bread.
After bread, your fears or revulsions should have dissapated enough to allow you to finally do one droplet on your finger straight to your mouth. And voila!
