title: The GAy MEn Sex StudieS: design of an online registration of sexual behaviour of men having sex with men and preliminary results (GAMESSS-study).
abstract: BACKGROUND
  There has been limited investigation of the sexuality and sexual dysfunction in homosexuals by the sexual medicine community. The purpose of this article is to describe the methodology of the online GAy MEn Sex StudieS (GAMESSS) on the sexual behaviour and sexual dysfunctions of Belgian men who have sex with men (MSM).
  
  
  OBJECTIVE
  To describe the methodology of an online study that investigate sexual behaviour and sexual function and dysfunction in a sample of Belgian MSM.
  
  
  METHODS
  An internet-based survey on sexual behaviour and sexual dysfunctions was administered to MSM between April and December 2008. The questionnaire was a compilation of the Kinsey Scale for Sexual Orientation, the Index of Premature Ejaculation (IPE), the Erection Quality Scale (EQS), the Female Sexual Function Index (FSFI), the Brief (Male) Sexual Function Inventory (BSFI) and the Gay Men Sexual Addiction Screening Test (G-SAST). The analytic sample comprised 1,830 Belgian men aged 18 years or older, who reported having sex with men.
  
  
  CONCLUSIONS
  The use of an online questionnaire is a convenient way to gather information from a hidden population such as MSM. The anonymity of the participants is guaranteed. The collected data can be easily analyzed. With this online study, we aim to detect variables in sexual behaviour (SB) and sexual dysfunction (SD) that can help to improve care for MSM. Belgian MSM have a very active and varied sex life. They are rather promiscuous and do not always practice safe sex. This behaviour poses a high risk of spreading sexually transmitted diseases. Additional research in this MSM population is needed.
