TMI!!!

So I just had sex with my husband (told you it was tmi hahaha) and lately he's had a hard time cumming. So this time when he finished I asked plain and simple "did you get to finish?" And he didn't say anything so I was just waiting on an answer as he's walking to his side of the bed. Then I feel it start to drip out and I said "oh it's dripping haha" and he responded with a sarcastic "yeah, did you cum?" This threw me for a whole loop and I'm like "what?" *no answer* "Did I hurt your feelings?" And then all he's said since then is yeah a little and I can't get him to tell me why. I told him "I know you've had a hard time with that, I just wanted to make sure you came too. It wouldn't be fair if I did and you didn't; that's the only reason I asked. I felt you tense like you did but I wanted to be sure is all, " and he just kinda got in bed and said "its because I've been having a hard time cumming lately" and I'm like ok that's a start, and went off to the bathroom real quick. When I came back he was laying down and I asked if he was gonna go to bed upset (which why would I want him to? I don't want to let him do that and get a restless nights sleep or build some sort of resentment) and he never responded. So I'm asking: do you think he's just in a little man period funk? He's been up since about 9am- it's currently 3:16 as I type this haha- maybe he just needs his beauty rest? Even still you don't just ignore your wife. Right now I'm just gonna get some sleep and try again in the morning. I'll try to provide an update later if anyone is interested/ curious/ whatever have you.
