With the obvious global aging trend, the issue of elderly care for lesbians has become a serious, neglected problem. Due to homophobic atmospheres or the lack of support from children, many elderly lesbians are forced to face endless loneliness in their later years. In this context, a lesbian sex doll is not only a companion to alleviate loneliness but also a final support in their later years. Research shows that the physical presence of the doll can evoke caregiving behavior, thereby triggering positive attachment and emotional states.
