I don't think this only applies to guys, am sure there are women who also have the same problem. Anyway these kinds of men who feel out of place when they are in the midst of women, i would say are probably guys who have been brought up by their fathers mostly., or men who have grown up in families without sisters. Parents impact their children in so many ways when they grow up, and when the children miss the presence of both or one parent, there is the miss in their lives when they grow up. so men will feel awkward around women because they don't know how to react towards them. Women are soft beings and when a man has not been taught that soft side he will probably end being cold towards women. Such men need to sit with their mothers or aunties someone they feel close to, and can talk to without feeling embarassed, just open up to that person tell them your fears and they will guide you through the whole process. the women will go and extra mile and even tag you along when they go out, so that you can get comfortable. before you know it, you will be as confident as a lion.
