"Good" is subjective and up to the girl (and possibly her partner)! But it's definitely natural and shouldn't be something considered shameful.
This. It's not physically harmful and, as far as I know, doesn't provide any benefit either (though some women find their orgasms are more intense when they squirt - whether it's the better orgasm causing the squirting or the other way around, I'm not sure). Aside from that, it's all subjective. Plenty of people find it very hot, others not so much.
I have had a few remarks made about my squirting that has made me not want to at points. At one point I was ashamed but now I make it clear with potential partners when sex is brought up that I am a squirter. If they can't make me squirt I will do it myself no orgasm for me is incomplete without squirting Some men are into it while others aren't. So far the one partner I have LOVES that I can squirt~
Like others have said, it's all subjective. As a girl that has squirted, I find that it's extremely pleasurable to squirt, so yes I say it's good if it happens. There's absoulutely nothing wrong if it doesn't though.
