But what does that mean for your new, budding, happy, "perfect" relationship?
Wmen ask me all the time about what they're supposed to do about the men out there who say they only want younger women in their profiles.

[Why more millennials live with their parents than with a spouse or lover] The decline seems likely to continue: According to the latest data from the Centers for Disease Control and Prevention, the portion of high school students who have had sex fell last year to 41 percent from 54 percent in 1991 and about 47 percent in 2013.
The portion who reported sleeping with multiple partners also declined, from about 19 percent in 1991 to about 12 percent last year.
