Ezekiel 25:17

In general the majority of guys never fukk above average girls, or for a sustained period of time.
Being on top of your game is difficult unless you get into the rhythm and make winning a habit.
To answer op, it depends how deep your sauce is. In general I'd say mid 30s. But if you really on game, that could run to your late 40s and beyond.
The mid 30s men in my family don't look mid 30s. If you mid 30s and washed up, then yeah you might as well cut yo losses messing with young 20s women
Again, it depends on what you look like. Looks, diet, and game.
