本研究主要在探討愛滋病男同志的親密關係、性慾互動歷程及高危險性行為。本研究採「立意取樣」及滾雪球抽樣方式選取研究個案，進而運用深度訪談及門診參與觀察互動等方式蒐集資料，時間約為一年。研究對象共5人，年齡介於23～53歲之間，學歷為高中至大學，其中1人曾有一段異性戀婚姻，生下一子，兩年後離婚，其餘4人均未婚。5人均為已確定診斷為愛滋感染之男同志。研究結果發現：一、本研究中多數受訪者並沒有因愛滋感染而改變原有的性行為；二、男同志對性慾互動的需求高於親密關係的期待，表現方式為性愛分離，享受性多於愛；三、對固定性伴侶因為害怕愛滋身分曝露，會因對方要求而不戴套，對於砲友因自身安全考量，戴套機率較高；四、智慧型手機交友及網路使用已成為新世代同志的交友管道；五、性慾凌駕於安全性行為之上，受訪者未感染前，自覺幾次不戴套感染機率應不高。
