I'm 16 and he's 25 is it wrong?

Like I said in the question. He's 25 and I'm 16. We went out last night within a group and I ended up sharing a bed with him while everyone (including myself) was drunk-nothing happened (except for kissing) , I remember and I woke up fully clothed. But now he's saying he wants to be with me but I don't know, I'm always seeing negative reactions to older boyfriends; but, he was so sweet, he made sure I didn't hurt myself on our way home and stopped whenever I asked him too.
