Orgasm...Did I experience my first one or not??

I'm 27 and just started to really explore my body with different toys. I have a favorite that I use often but this particular night I was playing with it and felt my whole body get warm. It was the best feeling I've ever felt but I'm not sure if that was a real orgasm. I know a lot of women haven't experienced them but those that have, will you please figure out what happened??!! Lol
