is it weird he's doing this?

Is it weird he's changing up the sex? I mean I'm up to try anything but we did this thing the other day and today where as we're having sex, we ask each other how our days went. We also cum at the same time too.. (I'm pretty sure he's controlling when he releases) I think it's hot. Today after we finished he still wanked one off after we just had sex (is that normal?) I always kiss him and make out with him when he does that but he moaned my name while doing this today. He's never ever done that before in the 1 year we've been together. Then he's like: my girlfriend is so fucking sexy. Why is he spicing it up? He recently asked me about my fantasies and he was wondering about the previous guys I've been with and done things with. He told me about the girls he was with too. Idk why he would bring this up. He made me upset and he also told me him and his ex are in the past like basically that he's over her. He said he loves me now and he's been saying I love you since last month when he started again. One thing I don't get is that he told me is that when they were together he thought she cheated on him but she told him that she was just playing mind games. He said she also cheated on her boyfriend over the summer (before we were together in 2015) with him. My bf said the guy she's with now treats her like shit but the girl is always tagging her bf in memes and sharing pictures of the fun stuff they do together.
