Premature ejaculation is typically thought of as a problem for men, but in a Portuguese study a number of women reported premature orgasm to be a problem as well.

LiveScience’s Stephanie Pappas reported on Tuesday that in a survey sent out to a sample of women age 18-45, that of the 510 who responded 40 percent had orgasmed earlier than they would have liked at some time and that 14 percent “reported more frequent premature orgasms,” making them “probable” cases that could require clinical attention.” Yet another 3.3 percent “met the criteria for having a dysfunction due to premature orgasm.”

The survey also asked about relationship satisfaction and found no link between that and premature orgasm.

Premature orgasm is certainly more typically associated with men and, indeed, Pappas notes that inability to orgasm is “likely a more widespread problem. A 2010 study of American women found that trouble reaching orgasm is the most common sexual complaint in women, with 54 percent of 18- to 30-year-olds reporting this problem.”
