what's going on!?!?

Hi ladies!! I haven't posted here in a long time but when this issue came up and I couldn't talk to anyone about it I knew I had to come here! I feel like I'm crying and running to you all haha 😂😂😂 okay so.. my partners Apple ID is logged in on my phone (he knows, he did it) and I was scrolling through games he has so I could get some (he has good taste) and some apps came up that he had purchased eg. eHarmony, Snap Save apps, a porn game one! And a porn and masturbation addiction app.. now I don't have an issue with him watching porn we are open about it we both watch it in our own time but for a while he's been telling me he "hasn't watched it in sooooo long!!" Yet he keeps coming up with new sex positions that he "seen in a porno a long time ago" does it seem suss or is it just me worrying .... please help.. what do I do!? 😞
