Well, you know, it all stems from people not being honest going into the thing. You get these guys who have no clue as to why they're getting married other than some vague notions about access to sex and it's what "you're supposed to do." Then you have women who bend themselves around like a pretzel to please the guy. Sooner or later, one or both of them wake up. Sometimes they both wake up together, which is always amusing in an extremely dark kind of way.
For the past 40 years,the old,languishing FREE LOVE MOVEMENT took off,so sex can't really be the reason men marry now.
The "what one is supposed to do"? doesn't work either.Time was,when both were a valid supposition;not now.
Both men and women have been known to NOT be themselves at all,during the courting game.You can't blame that on one sex...especially with all of the metrosexuals and girlymen around now.
Instead,look at what passes for entertainment today. YUCK! In the past,movies were the great "teacher" and through them,many learned how to behave;what was moral,what was mannerly behavior,even what love and marriage was like.fast forward and what do people see today? "SEX AND THE CITY" ,MTV,and moronic "reality" shows,that bring everything down to the gutter.
