Why wouldn't she? If something isn't working the time to mention it is then not later. I've tried all sorts of things with partners. Sometimes it works... Sometimes it does nothing for me. I just let them know "hey this isn't working, maybe we should do something else?" And it's fine. Mature sex is about bring able to communicate. As to laughing... Sometimes you just have to when things go wrong. It's not about mocking, it's the fact sex is funny and having a sense of humor is often the best way to handle when things go wrong.

Doggystyle ≠ anal?

Doesn't matter, had sex.
