We are all pushed the mantra that you should last long in bed.
The question is how long is long enough?
I fucked a girl today and our sex lasted 20mins. She's fit and in shape but she told me she was tired after two sessions. (And no it wasn't because she hated sex with me

)
So in my opinion you don't need to last longer than 20mins max of intercourse. With foreplay that can easily get up to 30mins. That is plenty.
Any thoughts?
Again it doesn't matter if it's with a WG or a normal woman.
