It seems much more likely that this skeleton, in life, filled the cultural role of a woman. And I seriously doubt that this role was relegated to sex with men. It seems far more likely that this skeleton lived as a woman and was regarded as either a woman or as a feminine figure (such as other non-man or non-woman roles including berdache).

Not to mention that apply contemporary terms like homosexual or transsexual to previous periods is insensitive to the culture of origin.
