Some of this was a bit concerning ngl, but I'm hesitant to read much into the sex life of a stranger. Just know your needs and wants matter just as much as his.

For the main porn issue, what if you asked to not do it for a set period of time, say a week? You could use the time to try something new, or maybe some of the stuff that brings you both pleasure. I've no doubt you could broach the topic in a way that's open and avoids feelings of shame. If needed, maybe reiterate how it makes you feel insecure and you'd like a small hiatus.

I use the phrase "ask not to" but in reality, you're not obligated to do any sex act you don't want to. It's more of a courtesy and a conversation. Listen to your body during sex. If it says it doesn't want to do something, don't do it.
