It would be nice if men actually said what they thought and didn't freak out when women say what they think.
...and if they were more honest about expectations they have in relationships...
For instance, if a guy just wants to have sex with a woman and doesn't plan on anything more serious (especially if the just sex thing is mutual), he should let the woman know that. Women aren't always looking for a lifelong partner either. Getting laid just for the hell of it because there is mutual physical attraction is cool.
Also, what is it with men and being in a 'relationship'? As soon as a man hears that word, he runs away screaming. Don't they understand that any contact with a person (be it sexual or otherwise) entails a 'relationship'?
