What is an ideal sex duration?

We should all know that, There is no set time for how long sex should last. It can vary greatly, depending on preference and a range of other factors, such as what a person considers sex to be. People define sex differently. One person might only consider it to entail penetrative intercourse, while another might consider sex to start with the beginning of foreplay and last beyond each partner’s orgasm.

Evidence of how long sex tends to last is difficult to obtain, even anecdotally. A person might feel pressure to lie if the duration of sex for them differs from perceived cultural norms.
