Is it OK for guys to bottle up their emotions?

I hear allot that girls can't keep their emotions inside and if they do they'll end up being really bitchy, or other problems will occur. But I never hear of guys having issues with holding in their emotions. Are you suddenly a wimp if you don't keep everything inside? And girls what would you think of a guy who talked about his emotions on occasions? Discuss.

Over time it seems like as boys grow into men they lose their feelings. I myself feel a lack of sympathy for most things, which I notice was not always the case when I was younger. I wonder if its society around us that makes us this way or is it natural?

It appears to be true. Society has turned us all into robots made in a factory line!
