why are girls so sensitive/jelous?

Well let me put it to you this way, are you saying if your gitlfriend was staring at nice looking males it would not affect you at all...I know for a fact guys do not like it at all in fact I have seen guys fly into a rage when their girlfriends have done exactly what they themselves do infront of them, in fact I have told girls to try the experiment and they have all said their boyfriends or husbands have not liked it at all. Women don't normally do it to their boyfriends and husbands because women are more sensitive to other peoples feelings than men plus usually women when they are in love with someone no-one elses looks so good to them...as for the make up men spend a lot of time ogling women on TV and celebrities who wear the makeup so they often feel they need to improve themselves to come up to their mens attractions....be more sensitive and you will be surprised...
