help me please omg

ok so my boyfriend and I started dating fairly recently and he came over the other day and we were making out and he was really turned on, but i didn't want to do anything with my family home, so i thought i would be "adventurous" and take him out to a study hall near my house and go to the bathroom bla bla bla.

Now, ya girl here is a super virgin all i've done before this was kiss, but he isn't so i felt really awkward about not knowing what to do so i was trying to be all confident and i was like "show me what you like" so he uses my hands on his dick for like a minute but then he stops me and says it's a weird place to do this and that we should leave. I haven't stopped cringing someone please help me i feel so embarrassed and i'm afraid it was because i was bad at it or something ahhh.
