排灣族人將琉璃珠作為結婚儀式中的重要物品之一，亦為該族群的重要文化產物。對於琉璃珠近年來雖有較廣泛的探討，但仍較少研究將性文化議題納入，並做進一步整合性探討。性文化包括與性相關的風俗、信仰、知識、藝術、道德與法律，以及社會成員經由學習得到的習慣與能力所構成的複合體，涵蓋的範圍極廣。因此，本研究聚焦探討排灣族拉瓦爾亞族傳統琉璃珠的性文化意涵，從多方蒐集的史料與文獻加以整理與分析，以瞭解排灣族拉瓦爾亞族傳統琉璃珠在原住民族社會文化脈絡中與性相關的神話與意義，以及性文化意涵。彙整文獻結果，本研究依據婚聘、戀愛交友信物、性行為和生產進行傳統琉璃珠之歸類，發現與戀愛交友信物相關的傳統琉璃珠有2顆；與婚聘相關的為6顆；與性行為相關的有1顆；與生產相關的則有1顆。由於傳統琉璃珠穿梭在拉瓦爾亞族人的文化脈絡下，藉由涵化過程連繫著與性相關的文化意涵，再加上神話傳說，更造就了琉璃珠的豐富性與神秘性。

The Paiwan regard glass beads as one of the significant articles used at wedding ceremonies, as well as culturally important products of the community. For the past few years, people have generally discussed glass beads, but seldom included them as a sexual subject or further discussed their integration. Sexual culture includes not only the customs, faith, knowledge, art, morals, and laws related to sex, but also a complex consisting of a wide range of habits and abilities of members of a society. Furthermore, this essay focuses on the sexual implications of traditional glass beads from the subfamily Raval of the Paiwan. We collected historical data and literary reviews to analyze the social and cultural contexts of aboriginals, myths and implications related to sex and sexual meanings of the traditional glass beads of the subfamily Raval of the Paiwan. This article discusses glass beads used as tokens for marital engagement, love and friendship, sexual acts, and reproduction. I found that there are two traditional glass bead tokens related to love and friendship, six related to engagement, one related to sexual acts, and one related to reproduction. The cultural context of traditional glass beads in the subfamily Raval is associated with cultural meanings related to sex by the cultivation process and with myths and legends about fertility and the mystery of glass beads.
