<human>: Can you condense the text into a few key points?

We've been together four years, lived together for three. 

We've always had a great sex life and he is usually very attentive to my needs/pleasure. He went down on me all the time and made sure I came when we did the deed. Lately we've been going for 3-4 days during the week without sex and then we'll have sex (or he gets off from a BJ) 5-8 times during the weekend. For instance we went from last Sunday-Wednesday without, I gave him a BJ on Thursday and we had sex Friday.

This past 3-day weekend we had sex probably 5 or more times, and I gave him 4-5 blowjobs as well to completion. The first time we had sex he went down on me (kind of lazily), but I came. The rest of the weekend he didn't- I would go down on him then he immediately wanted to fuck me, whether I was turned on/wet and ready or not. On Sunday night we began to have sex and he stopped halfway through and said he'd pick back up in the morning because he was tired from having orgasmed 3+ times within 24 hours and said it was "uninspired". Ok.

So yesterday he got another BJ and half-assed sex with me once. I'm just getting frustrated when we  go 4 days without and then I get *him* off multiple times and he doesn't seem concerned with getting me off anymore. I don't know what's changed. He was kind of quiet last night too. Should I be concerned about something?

I know I need to communicate with him but we've never had troubles in this arena before, so I'm out of my element, and I don't want to hurt his feelings. I like pleasuring him so I don't want to withhold things like BJs, but geez. I want to get off as well, KWIM? Please advise me. What's going on and how do I go about remedying it?
