You and Harry have had quite a romantic and passionate night, you're used to doing it with him and he with you and you've always used the necessary things. In the morning you woke up a bit shaken and asked him if he used protection last night, he looks at you and says.

"Ehh I think so, I don't know, yeah, yeah I would say yes."

You look at him incredulously since he doesn't know if he used it and he doesn't sound convinced enough either. (Sorry if this is obscene)
