Often, yes, but it depends on your refractory period, the recovery time after ejaculating, which ranges from minutes to hours and gets longer with age. It’s a workaround, not a fix.
“Just go twice” is one of the oldest tips around. There’s something to it, but it comes with conditions, and it doesn’t change the first time at all.
The refractory period
After ejaculation, the body goes through a recovery phase called the refractory period. During it, getting another erection and coming again is difficult or impossible. According to Healthy Male, an Australian men’s health organisation, it varies from a few minutes to many hours between men, and it tends to get longer with age. There are no drugs that shorten it.
Why the second time can be longer
Once the first ejaculation is out of the way, the urgency is lower and you’re usually calmer. That’s why many men find the second round lasts longer. I couldn’t find solid research measuring how much longer, so take it as a common observation rather than a rule.
Why it isn’t a real answer
It only works if your recovery is short enough, and if you and your partner want to wait and go again. With age, that gets harder. It also leaves the first time exactly as it was, and for a lot of couples, the first time is the one that counts. Some men end up building their sex life around the workaround, and the pressure on that first round stays.
A related trick
Some men masturbate a few hours before sex for the same reason. That’s a different question, and I cover it in does masturbating before sex help?.
What I’d rather aim for
Being able to choose the moment on the first round. That’s what I trained for, and it’s trainable: see can you train yourself to last longer?. If you also find it hard to get a second erection, or the first one is getting less reliable, mention it to a doctor: erections are worth checking for their own sake.
