Weird Sex

Ok so me and this guy was in the middle of having sex in his living room...it was getting spicy. We were getting into it, all of that good stuff. The first time he just got up suddenly, went into the kitchen, then came back and we started back up. Then we started back up and then all of a sudden he was like “We gotta finish this another day.” Ummmm...ladies what does this mean? I didn’t give him a reason to do/say that.
