Fingering? Sorry if TMI

My boyfriend fingered me last night when we were in his car. It felt amazing but the position was kinda uncomfortable in my opinion. He was asking me if he was doing it right and I said I thought so because he made me feel amazing. However I don’t know if he was doing it right because this is my first boyfriend and first time going this far.

Last night after he went home I immediately peed a lot, is this normal?

Also what can I do to make him feel good? He’s making me feel so go that I want to return the feeling.
