I think your guess is correct.
However, the consistency of your cum will change quickly and even after a couple of minutes it won't look that tasty anymore and it will cool down anyway...

You might try to ejaculate without orgasm. Here you need some time. Masturbate and just stop before you are about to cum. Then again and again. After a while you will feel that your spunk comes up and you ejaculate a reasonable amount of cum - it won't squirt though. But you will be still horny. And believe me you will be kinky enough to drink your cum instantly.

Enjoy!
