I orgasmed thinking about this!! Is this normal?

Last night me and my boyfriend were having sex, he doesn't dirty talk much so in my head idk why but I was imagining that he was dirty talking saying stuff about other women touching him sexually! And it made me reach orgasm!

The thing is I am an extremely jealous person and if a woman were to touch him in real life I would 🔪 a 🐶

So I find it really weird the thought of that made me orgasm. What the hell?
