It goes both ways for “not attractive” women as well.
This is purely anecdotal, but all of the “not attractive” men I have known who complain there’s no women online for them are only talking about women who are more attractive than them. The ones who don’t complain have realistic standards and can find matches. It also tends to help they don’t have s shit attitude.
But it’s still a numbers game. More attractive people get more matches, but that doesn’t mean those are quality matches. I guess if all you’re looking for is casual sex it makes a difference.
