Why do shy guy hide their feelings?

Answer 1

My opinon is because they are shy and they don't want to get embarassed if they do show their feelings and I think they are afraid that if they tell you they love you then you would say you don't feel the same way or you are not ready to have a b.f

Very True, I would also add that shy people can also be quite insecure so they are afraid of rejection. By keeping to themselves and being thus shy, they don't get rejected by anyone. So this can apply to men or women either way. They also hide their feelings because they don't know how to play the so called "love game" the which most people seem to engage in relationships. They lack the social skills or feel they don't know how to flirt, tell jokes or establish a link very easily with women so they give up. A lot of shy people are comfortable around people they know well or are good friends with. In time they would probably open up but to get a "Shy person" to pour their heart out to you would be very difficult, male or female. You would probably have to make the first move emotionally or give them some serious "hints" that allow them to know you want them to express themselves. In time with gained trust they'll accept you as a person who they won't hide their feelings to because they feel it's ok or that you want them too.

Also you may be mistaking Shy for reserved. There are a lot of guys out there who will never express their feelings because to them that is something that is theirs and no one else's. I really don't know how to put this but it could just be a masculine thing. Us reserved folk keep our emotions to ourselves. While a guy could be pretty outgoing at times and not afraid to walk up to other people and start a conversation, they may never emotionally open up to them due to seeing the inconsistency of it or because they know some people like to manipulate others emotions sometimes even for kicks. It's also a defense mechanism to protect ones mental self.

Answer 2

Because the main reason of shyness is the fear of doing something wrong. And somehow, a shy guy may think that if he shows up his feelings, may not be mutual.
