why cant i communicate properly with guys?

Oh my god I'm the same way! I'm really shy when it comes to guys. I have to get used to them first before actually making a conversation with them. It kind of broke away when I had to work with a group that had boys in it, so I was forced to discuss things with them. rather than always talking about the project I practiced making small talk when our group had the time. And confidence is another thing, I can't really teach you that, it's something you'll have to find in yourself, but it plays an important role if you want to get better.

you should practice....until u feel more comfortable...it may be you never feel totally comfortable in your life about it but you can improve it...you will find some guys that are not even attractive to you and speak to them regularly...be friends with them...learn more about them...and step by step you will find your way thru the years...its the only way...socialize with guys and improve your shyness.
