first time for everything?

okay so i was super horny last night and again tonight. so i was watching some porn and i’ve never fingered myself bc it just doesnt feel very right/comfortable to me. so i was trying new things like grinding into a pillow, squeezing my legs together, etc. well i found a hot video and i started to rub myself pretty fast and literally 5 seconds later i could feel the build up and then it felt like i had to pee and i got lightheaded and my body got super warm and like a super intense feeling. but then it stopped and i just had to catch my breath for a minute. i tried to do it again but i couldnt seem to get wet so....was that an orgasm or ??? someone help plz (p.s. im 17 dont judge)
