Appropriate dating age range
According to Dataclysm, a data book by author Christian Rudder that analyzes dating trends, found that after 20 years of age, women become more and more open to dating men older.
And unlike men, as women age, their desire to date younger people wanes.
Your friends are going to be really impressed that you can date a younger woman. She's been around the block a bit, but she's still not a luscious, incredible woman over the age of 30 yet. So at 46, you finally get to have incredible sex with a beautiful, mature woman -- but you have to wait 46 years to do it, according to this urban legend. That makes sense, considering the fact that an 18-year age difference is something to which you should really be accustomed. So finally, after all these years, you can actually date the kids you knew when they were kids. That's exactly what women are looking for at that age. Here they are, still looking great, young and fantastic, and there you are with your skin sagging everywhere. There is a negative connotation to a woman dating a younger man. Maybe try dating people who are within seven years of your age -- on either side.
This results in an unfortunate situation for women as they age: During their younger years, they're highly sought after.
But as they grow older, men's tendency to seek younger women leads to an ever-shrinking dating pool for older women.
A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years.
According to this rule, it would not be creepy for a 30 year old to date a 22 year-old, but an 18 year-old would be off-limits.
