Just my experience as a mid 20’s woman in the US. After high school or college, making new friends is impossible. You can have the best conversations with coworkers then never get invited to stuff outside of work and get brushed off when you try to make plans. You can meet existing friends’ mutual friends, really hit it off, then never see them again. If someone lives more than 15 minutes away, they won’t make an effort to hang out. People would rather hold onto toxic friends from high school than meet people as an adult that they’d actually vibe with. As a woman I KNOW it’s easier for us to get hookups and relationships. But male loneliness is also rising and tons of guys I know have no close friends or even acquaintances.
