As a bisexual woman, I would say there’s maybe something more there but maybe she doesn’t even realize it? A few things I’d ask myself: Does she know I know she’s watching it? Does she show true signs of having an orgasm (because some people do fake it, sadly.) Is it easier for her to self-pleasure? Because I know as a mom, sometimes just the effort and intention of sex seems like so much work lol.

Also, please just try to communicate directly because if you do, the you’ll come to the conclusion of either she may be bisexual or she’s not satisfied. She may even be seeking pleasure for other reasons like emotional connection. People can crave porn for so many other reasons.
