Did he cum?

I guess he'd be the one that would know for sure if he came or not. Just ask him and he should tell you. I mean you guys should know each other good enough to ask intimate questions if you're into sex already. If he said he didn't come why are you worried? He said he enjoyed it so just leave it at that. If you plan on continuing to have sex with him I hope you guys start communicating with each other on what's going on. Also, I like how he told you that he expects to have sex at least once a day like it was gonna be some obligation of yours now. Also, it sounds to me like he's not very high strung if it takes him that long to cum. By any chance did you tell him how long it takes you to orgasm? Personally, I think he's gonna wear you out, and have you had any romance in your relationship?

Guys can hide orgasms.especially if they have masturbated a lot in their past.

at least I can .

Yes he could have cum. when you are turned on enough it is the goal to keep going after a come to well "cum again". I would take it as a compliment

If you went to bed and didn't get up after and then in the mornight there was water coming out of you then he cumed. If you got up right after you would see it being thinker
