Penn State Erie researchers Eric Corty and Jenay Guardiani conducted a survey of 50 full members of the Society for Sex Therapy and Research, which include psychologists, physicians, social workers, marriage/family therapists and nurses who have collectively seen thousands of patients over several decades.
Thirty-four, or 68 percent, of the group responded and rated a range of time amounts for sexual intercourse, from penetration of the vagina by the penis until ejaculation, that they considered adequate, desirable, too short and too long.
The average therapists’ responses defined the ranges of intercourse activity times: "adequate," from 3-7 minutes; "desirable," from 7-13 minutes; "too short" from 1-2 minutes; and "too long" from 10-30 minutes.
