Yeah, I was wondering, is there a big time difference between cumming when you jack off and having sex? Or if there isn't how can I last longer? Because I only last like 1-2 mins when jacking off (never had sex yet)
About Lasting longer
Time to cum when jacking off and in real sex can be very different for any particular guy. Jacking off can be quick and sex slow, or the other way round (or both quick or both slow).
It might be a good idea, though, to try taking longer by using the stop-start technique.
