top or bottom

[korean]

i was wondering
if you guys are able to cum on the bottom with a girl on top?
i went to one of the incall, the girl asure me that no guys can cum, while girls riding on top.
I having difficult time cumming in the MP and SP, but i was been lazy....mostly i just lay there, and the MP or SP ride the whole show.( i figure i pay her to work, not paying her so i can work)
so i just want to find out, if the girl just been bull shitting me or is that the problem of my never cumming problem?

I've met some incredible SPs over my hobby years. On average, I am pretty good at holding back, but I think it's all about the skill. They rode me like a champ, and I just couldn't last more than 2 minutes.

Usually I am able to cum on the bottom with a girl on top...big. But other times when I am not very in the mood (nothing to do with the SP), I simply can't.

Maybe I am pressuring myself to have the best finish and performance, make her whow!

I prefer the SP rides the whole show, not because I pay her but I figure out I am not good at finding her "happy button" when she's riding

Regarding the duration, I could hold back as long as I can cause I feel very "insulated". Sometimes I suspect the SP doesn't like me to hold that long and change the position by herself.
