For me it depends...if i am worked up then usually in a few minutes. But sometimes it takes longer or i want to tease myself to make the cum more enjoyable.
Masturbating, I usually take my time -- but anywhere from 15 minutes to well over an hour Handjob -- I usually can't Blowjob -- anywhere from 10-20 minutes, I guess During sex -- not long enough, that's for damn sure
jacking off- can be as long as i want but could be as quickly as 3 minutes if im in a crunch. handjob- long time, if even possible blowjob- 15 minutes i guess. fucking- pretty quickly. (i dont care about lasting a long time with this one. its not like i have a girl i need to please)
