First time it happened to me

So I am up late, watching porn, getting in the mood. I take out my dildo and start from there. Was great. I’m enjoying myself, I’ve stopped watching porn and decided to go alone with my toy.its hitting the spot, I’m moaning loud and I’ve decided to record myself (don’t ask why) next thing you know, I’ve squirted. I kept going and eventually stopped (I’ve got it on camera)... I don’t know if I’m shocked or surprised at the fact that I’ve fucking squirted 😂😂😂 I keep watching it on replay. I kind of feel weird about it though. Is that normal?
