Why do some guys act immature when around girls?

Most men will stay that way. they act grown up around the ladies...and then with the boys they go back to being a child with no cares This is a pretty unrealistic generalization of the male condition, obviously the product of an emotional response to an event in your life. I disagree. The majority of men are childish and this characteristic is prominent mainly around other men. The truth of the matter is both men and women are more relaxed when they are with their own sex and they can act what you are calling "childish" but it's just pure fun. Life is far too serious these days so if one wants to be a little silly or "childish" what the heck! Women go to male strip clubs and I've been to one with a group of friends and couldn't believe my eyes when I saw many women acting like total idiots. Don't always blame the guys on this one! I love the post above mine. I wouldn't say men get too childish around each other, but reach back into their youth and just have fun. Women do the same thing. My girlfriends and I have a blast and act whacky at times just for the sake of it. It's healthy fun and hurts no one. Life is too serious most of the time and we all need to kick back and be kids again. Answer Men love to fight. but to me this is only natural. It's a sportsman thing.
