It varies, the same as it does for men. Every female has different tastes, and prefer different things done. If you're good, 20 mins or so? ;)
They say average is 20min but it of course depends on what you do and many other things.
A girl should be pregnant for 9 months and then give birth...Is that what ur asking?
Everyone is different
It takes about 6months
Just take it off. Take it off.
You cannot MAKE a girl take off her clothes. You get into a proper relationship with the girl first. Getting her to take her clothes off against her will or if she isn't comfortable, believe it or not, is a form of sexual assault. You will be jailed for a very long time if you make a woman do something she doesn't want to do. Doping or getting the woman severely drunk and making her strip could even be rape.
Shave it all off girl
As long as you make it take.
To ask a girl to take off her clothes I would ask "hey i wonder what you would look like naked. could you show me?"
Take the sandels off
Assuming you mean orgasm, every female is different. It can be less than 30 seconds from the start of sexual arousal to never.
If a girl takes her shirt off in front of an guy then its a high chance she likes the guy
