I am M28, she's F30.

Quick context: we had some days of feeling resentful at each other because of reasons. I wanted to have sex and she was open, but with conditions (go quick because the market is closing, for example).

So after two or three attempts (and after she gave up on the market) we finally started.

I'm a passionate guy, I can't avoid it. I constantly move her from one position to another, I kiss. A lot, everywhere. I speak on her ear. I massage her tits and nipples and ass. I don't plan anything, this is just what I do naturally, and as far as I know she loves it. It usually last enough for her to cum multiple times.

But this time it was very different, because because we had a really bad week of discussions or whatever. So I didn't allow for her to suck and eat me (which she usually does and loves) and instead, submitted her and started to fuck her. I charged at her nonstop with barely any kiss or words for a short period of time (maybe 5 minutes) before I finally cum. It was BY FAR my fattest cum ever and the less exciting of them. We both felt something was different but barely spoke about it. According to her, she finished too. I have no reason to doubt because she usually cums fairly fast.

I guess this is what most men do, from what I heard, and why some women are often disappointed at sex with men.
