There could be a few different reasons. The overarching answer is men don't often appreciate feedback and women really have no idea how they might react. Women also aren't usially taught to advocate for their needs or what sex is supposed to be. 

I imagine I'm gonna get downvoted or degraded for saying that but it's the truth.
