Am I supposed to be okay with this?

So I (16) was on my period and my boyfriend (18) was staying over and l think he was quite horny because we watched a movie and then went to sleep and he told me in the morning that he'd been spooning me in the night and he had been dryhumping my ass and he had a massive boner and he was hoping I would wake up... I think I'm okay with it, but I was unconscious and unaware it was happening so is it not okay? I'm kinda chill with it but I kinda just wanna know everyone else's opinion ???
