Depends what you mean by "squirts". Some men don't seem to squirt at all, if you are talking about the semen actually spurting out of the penis. If I've been edging, the spurts will be quite powerful but if it's a quickie the contractions of orgasm might only make it ooze out. Also it might not spurt if I'm masturbating again soon after an orgasm. I suppose out of a usual seven or eight spasms during orgasm, the first five or so will be spurts. A really good orgasm might have more than ten spasms.
Here's a pic of one of my better squirts.
