In the mentioned study, the researchers used artificial s2x organs as well as fake sp2rm using corn syrup. It was discovered that repeated thrusting could help get the semen out. Some men may experience pain as they continue thrusting because he could accidentally scoop out his own swimmers.
Meanwhile, a 2008 study conducted by therapists, the average s2x duration of five minutes could be viewed as good or bad, depending on the partner. Too short lasts two minutes at the most, while enough is from three to seven minutes. Most couples prefer from seven to 13 minutes, but while anything longer than 10 minutes is great, many think it is unusual.
