That doesn't make any sense, it would be better if there were homosexual and lesbian categories. Its just one of those annoying things about xhamster like when if you accidentally click on just one trans video it seems to change your preferences and recommendations to trans without even asking
I suspect,like everything on this site of late,it's a commercial decision. What sells the most. I,and others,have been aggrieved for years that our tribute videos are lumped in the GAY basket when it is patiently obvious they are aimed at (excuse the pun) and ,in the main,requested by women. Girl on Girl is mainstream dollar wise and semantics don't cut it against the mighty dollar.
