too far?

i went on a second date with a cute boy i’ve been talking to. at the end, we ended up kissing. and then kissing some more. and then he was grinding all over me while i was pinned against a wall. now, if we had been dating for a long time i’d be fine with this. but for some reason it made me feel weird, and i wanted it to stop. i just wanted to kiss, not anything extra. am i weird for feeling this way? should i be concerned he’s all up on me on the second date? am i being dumb? what do i say to him? i’m nervous lol
