ABOUT 80% of married men face erectile dysfunction five years into their marriage because of having a single sex partner, China Press reported yesterday.

It quoted Singaporean Dr Yu Wei Siang, who is otherwise known as Doctor Love, as saying that 50% of men faced the problem with their sex partner after being married for between three and five years and 80% of them after being married for five years.

The paper said it was normal for a married couple to experience low libido after having the same partner for a long period of time.

Dr Yu was invited by the Johor Baru Tionghua Federation to speak in Johor Baru about sex on Sunday.

Most members of the audience preferred to ask questions via SMS.

He advised married couples to take the trouble to look for new environment and stimulation.
