So I was reading this artikel and I wondered if u guys agree with it...

I think it just depends on the individual. I rarely get butterflies at all, about guys of any other situation. Some people get them a lot. I think its meer nerves than fear. You're nervous about saying something silly of not making a good impression. I guess u could substitute nerves with fear, but I prefer the former.
I don't think feeling butterflies of not has anything to do with if the guy is right for you.
