How long will you last during sex?
You can expect to last anywhere from 2 to 5 times longer (about 5-15 minutes, for most guys.)
But, this is individual and depends on several factors.
First of all, it depends on your timing. Most guys find that masturbating one or two hours before sex is optimal timing for them. However, you need to find out your own timing. Younger guys may masturbate and be ready for the second round in as little as 10 minutes.
Secondly, it depends on your age. As a rule, the older you get, the more downtime you’ll need between erections.
And finally, it depends on how exciting the sex is. If you didn’t have sex for a long time, you’re all amped up, and she’s hot you’ll certainly come a bit faster.
