**IM SO CONFUSED HELPP!!

Okay so me and my guy friend( someone i’ve been talking to for a while) were messing around and he was giving me head..then he started to finger me at the same time( mind fucking blowing omg) i’ve kind’ve experienced this with another guy but this time it felt different...it felt really amazing but it also felt like i had to pee but i didn’t...was i getting close to having an orgasm? Was it my g-spot?
