Ok idk where my head is at. Advice please!

So turns out I find it such a turn on when my SO looks at other women when we are having sex (well not actual women, extremely realistic cartoons) I'm a really jealous person, so I'd be a mess if he actually looked at other women ( we do not do porn, he also hates it) but like idk wtf is wrong with me, how do I go about this? lol. Do I just put those thoughts at the back of my head and never think about it again? As I'm pretty confused on my feelings here, we were having sex and I noticed he was secretly looking at these "women" very realistic half naked cartoons and I got soo wet and horny it was unbelievable. I have never been so turned on in my life. Any advice would be appreciated..!
