(F22) am feeling betrayed after bf (M22) turned on porn when I went to the bathroom during sex

Some context; we are in a healthy and living relationship. We just moved in together, fairly early (7 months) into a relationship mostly due to financial reasons. This has come with a few routine bumps and hurdles, adjusting to eachothers schedules etc. I would say this has been the rockiest part of our relationship this far, and it’s still pretty smooth sailing. We have had a few small tiffs mostly the ‘put the dishes away after you wash them’ type and we move through these pretty smoothly. Our sex and intimacy has taken a minor hit but I don’t think it’s anything out of the norm, but provides a bit of context for the incident.

About a week ago, my bf made a passing joke about me being in the ‘itty bitty titty committee’. In the moment I just made some kind of rebuttal joke throwing it back at him, I can’t remember exactly what now. At first the comment stung in a strange way, but the more I thought about why it stung the more frustrated I got. Honestly, I don’t really care about how my body looks. I’m an average weight currently and in the recent years have had several health issues making my weight fluctuate from overweight to skinnier than I was when I was in seventh grade. After this, I have learnt to just be thankful when my body works. I feel as if it was just kind of disrespectful having knowing the issues I’ve faced regarding my changing my appearance, and being intimate with said same body, it just quite honestly makes me go ‘ick why would you say that.’ I brought this up to him and he got really defensive and told me he was joking. I don’t think he committed a war crime here, I just kind of moved on from it even though it still peeved me.

Flash forward to the other night, we were having sex with me mostly taking the lead. I went to go grab him a drink and was gone for probably about a minute. After we are going to bed, and I usually put a YouTube video on his phone to fall asleep to because he has YouTube premium lol. I turn on his phone and he has it opened to Reddit porn. I’m just like uh oops. I’ve been really into evolution lately and went to open safari on his phone to try to find the name of Charles Darwin’s peapod monastery and it was opened to pornhub. Detail unnecessary I suppose but I feel almost guilty because it’s like I caught him doing something that’s actually nothing while I was just trying to nerd out with post but clarity. The double whammy had me a little taken aback to be honest and I asked him when he had time to get so busy. He told me that while I was gone to get water, he looked at porn. I don’t even have an issue with porn. I definitely watch more of it than him. But much like the previous issue, it feels disrespectful in a way I can’t entirely pinpoint? Like, I’m the naked woman who went to get you a glass of water and you go and look at several naked women while I leave for just a minute? I tried to mention it playfully and he got really defensive and said it feels like I’m punishing him by being upset because he shut it off right away. I’m not entirely sure what the root of what I’m annoyed about is, and I really don’t want to just keep being kind of annoyed about this while acting like I’m fine, especially because I feel like it could be a 5 minute conversation but I am lacking the words. Any advice appreciated I suppose, I feel like we have hit a walk in communication on this one.
