Why are so many guys whiny these days?

I realized so many guys are sooooo whiny these days and i see it at my work and school. i will admit girls do whine from time to time and tend to talk a lot but the whiniest people i know are all guys. WTF? and the sad thing is a lot of them have attractive g/fs that deal with that crap. some of them complain more than women who are on their periods. at least women say funny things sometimes when they whine about something, when guys do it it just sounds pitiful, annoying, and sad. how can some men in their mid 20s whine more than a high school girl??????
