Almost Came

I almost came for the first time ever just a few minutes ago and it felt kind of intense... my body was sort of twitching and it felt like my hooha was doing that too. I also felt like I needed to pee or was about to pee(which I heard is a normal feeling?) but I sort of stopped because I got scared.

It felt so freaking good and I wanted to keep going but I got scared thinking about actually have any sort of orgasm for the first time.(you can have a orgasm through masturbation right?)

Has anyone else ever chicken out like I have before and just decided not to finish? Or am I just weird?
