Yep. Definitely.
Picky point....I am not sure "mileage" is that phrase I would use. Just sayin'
From the woman's viewpoint (and some will tell you)... they are nervous and trying to figure out if you're a bad guy (annoying guy) the first time.
After one or two times, they know you, they like that you like them (you came back), they don't have to be nervous, they feel safe, they have learned at least some of your buttons, so they feel confident pleasing you....
[Note: There is no woman that every man likes. They all get some rejection. It is tough, as you know.]
There is something, sometimes, in the energy of the first mystery encounter. A spark. But I think this "clash of the titans" idea is over-rated....although I think it can happen.
Repeats, where you and she KNOW the chemistry is working....MUCH better bet.
Still, guys (that would include me and most women too)....sooner (me) or later (women usually) want a little variety too.
Even Filet Mignon would become boring if every night. But then, you probably don't "do this" every night.
Note: Cloudy explained well what I was feeling about "mileage". (Not that the OP really meant it that way.... not sure.) This is not the kind of thing IMO where you try to get "every nickel" out of her. Or to get discounts. It is a time to be generous in all ways, and usually women repay (all kinds of) generosity very well. Women are more generous. I don't mean be super-generous (throwing money around). I mean be (somewhat) generous in all ways.
