sex with a woman

HI, What you mean in your post?  I jack off about 9 or 10 times in a day.

I don't think there is a magic number that is going to make you last longer in bed with a woman. Being able to last is what comes with maturity and knowing how to control your body. Hope this helps. Good luck.

I think if you cum alone while masturbate under 60 seconds, with a woman I am pretty sure you could cum at 10 seconds. I don´t know your age but I guess you are too young, I suggest you take your time, go slowly please, maybe when you end your sexual development about 19 or 20 years old then you could cum after 10 or 12 minutes like mature men do.
