An adequate intercourse session lasts anywhere from 3 to 7 mins. Desirable one lasts 7 to 13 mins.
It doesn’t matter really as long as you and your partner are satisfied.
Again as I said, people who regularly watch adult contents who have a misconception about this.
1. Find out the cause. U need to see a doctor , therapist for that.
2. Stop-start technique .
This technique involves continuing sexual activity to the point when orgasm is about to happen,and then stop until the feeling goes
Next is the squeeze technique.
It involves continuing sex until the point of impending orgasm, but then squeezing the head or base of the penis to prevent ejaculation.
Another option is medication.
Don’t be afraid to talk about it, as it may affect your relationship.
