If racing to an orgasm is the goal, my wife can usually hit it around the minute mark using warm running water with little pressure.

My lady can orgasm in about 20 seconds - which makes her the envy of all her friends whenever they have sex discussions.

I'm pretty sure I've written on here before about her 'talent'. It has lead to a few unusual quirks in our sex life. For one, a pretty common kinky thing I do is to 'forbid' her from cumming for a time during foreplay or sex. This leads to her scrunching up her face and visibly concentrating on holding things back!

A second thing: she is often the one who wants sex to end. If sex passes the 10 minute mark (by which time she'll have orgasmed about 15-20 times), she often asks me to hurry up an finish!

@ 3 minutes orally usually. Sometimes though, she just never gets there at all.

About 5 minutes, and only with light caressing of her clit. She absolutely hates it if I try to make her last longer.

3-5 mins each time.

Pretty quickly
 

If she's already in the mood before we start, she can orgasm in 15-20 seconds from my finger on her clit. If I do oral, it's about 30-45 seconds. We rarely try to do it that quickly, however. A more common time frame is 1-3 minutes oral or finger.
If we're having sex, it depends. Sometimes 1-2 minutes, but sometimes not at all even in all of her favorite positions.

Audience
 

The surest way to get my wife to cum is to fuck her in front of an audience. We have done this many times, and she goes ino a trance. I am delighted I married a complete *****RUDE TERM REMOVED*****.

When she finds the dress she has been coveting on the sale rack 60% off, about 2 seconds.

I forgot about the shower massager. About half the time she cums in less than a minute, sometimes at first splash!
