Is throwing up even all that common within non-emetophobes? Is it a good or bad thing to go so long without it?

Why is it that people throw up 2-4 times a year contrary to emetophobes that throw up once or something after years on end? I went 14 years without throwing up until last year and I threw up for the first time and I remember thinking "this is not that bad at all." But its been a whole year now and pretty much the fear is back, my diet is practically normal in fact I even overeat sometimes lol. Anyways, I find it interesting that I haven't puked since then since I consider myself to have a fairly normal diet.
