Now going on to the next topic, relatability, it is your bread and butter.
I see relability as one ages to be more about superficiality. Women will consider a 6'0"+ and in shape guy relatable. So looks and fitness do matter in one's 30s just as much as one's 20s and maybe even more.
You must go to a big city or give up all hope for a great sex life.
After a man's 25th birthday.....
The presence or absence of a social circle in a man's life will determine his sex life more than the population of the metro area where he lives, so long as the area's population is over 150,000. When the area's population tends to go over 500,000-750,000, neighborhood choice matters a lot too. In larger areas, a man needs to choose to live in a singles dense area. In bigger metro areas, men who live in suburbs (generally oriented to those raising children under 18) are not going to be able to date effectively.
I have seen men with strong social circles in metro areas 300,000-600,000 date more effectively than men with weak circles in metro areas of 3-6 million. However, social circle oriented men tend to follow a more blue pill path and marry. Even extended serial monogamy behavior (trading out women every 1-4 years or so without marrying or having kids) is less common in men with social circles. Men with social circles tend to be more social circle dependent and won't risk alienating the social circle for future introductions. They'll stay in long term social circle generated relationships for fear of having to resort to swipe apps, random social media DMing, or cold approaching. These men have seen other men struggle with the aforementioned methods and don't want any part of that.
Being in a big city after age 25 puts in a man in position to have a sex life but doesn't guarantee anything. Once a man is in an area with 150,000 or more, the strength or weakness of his social circle will affect his sex life more than anything in the majority of cases. If a man stays unattached/marginally attached too long, his social circle will weaken as more of his contacts get into multiyear LTRs or married. Men tend to experience what I just described between ages 28-37.
Because pulling girls online is one thing but to learn daygame and nightgame so you can pull girls out of your league is something pays dividends as you get older. Especially now that online dating has been infested by bots and is practically pay to play.
Online dating is pay to play for men. Men need to pay for the unlimited swipes to be able to have a fighting chance. Most men only get matches on a fraction of 1% of their swipes, so you need the unlimited swipes to get a couple of matches, unless you're a 90th percentile + guy who is 6'0+ with six pack abs showing from multiple shirtless pics.
Daygame has always been a niche activity. Even 20-35 years ago, few men were randomly doing approach sessions at grocery stores, in malls, outdoors, etc. It's difficult to approach strangers at non-bar venues while sober.
The form of game that has changed the most since 1990 is bar/nightclub nightlife game. From 1990 until dating sites de-stigmatized in the mid-2000s, that was the most common place for stranger approaches to occur. Online dating and later swipe apps developed as an alternative to the challenges bar game presented in the 1980s-1990s. The bar scene is not fun at all. It can be difficult to get results from it. That's why "The Game" was so popular. Mystery and other PUAs were getting results from bar approaching. The PUAs realized that there were so many average guys (AFCs as they called them) who weren't getting results from bar approaching. There was one throwaway line in the book "Mystery Method" that says that the method is applicable in non-bar venues, though the vast majority of the book is focused on interactions that start in bars.
When Millennials became the dominant age cohort of singles starting in the late 2000s-early 2010s, they lacked the patience to deal with bar game that Gen X'ers put up with during the 1990s/early 2000s and Boomers in the 1970s-1980s. They thought efficiencies and effectivness were being created with websites and late swipe apps, but it didn't turn out that way.
