There are no valid stats. Everyone cites the lower bound of the study that 2% of accusations are false but the upper bound of that same study is around 30%. 

Issue is now that although the talk of consent right now is good, it is also heaping all of the responsibility on men to discern consent. 

She could come back to your hotel room, take her clothes off, jump on your lap but not tell you she did not want to have sex. That would make the guy guilty. 

In really women wait for men to ‘make a move’ and they say yes or no. They may even say ‘no’ but continue  wanting you to try again later. 

You could do everything right but she could tell a one sided story about how you ‘made a move’ but she felt pressured.

All the pressure on men to mind read, no responsibility for women to give clear consent. In fact they raise the bar so high that most men could be considered rapists because no one ever asks about ‘having penetrating intercourse’. 

Do women need to establish the same consent? Of course not.
