I don’t know how to ask him

So, occasionally my husband and I have rough sex and I get tied up, but I really want it more. He’s not as into it as I am. I reeeeaaaally want him to use me even just like once a month but right now it’s only like once every three months. He like rough sex but I guess I like it rougher. In the future, I’d also really like to try making a sex tape.
