While not technically women's wrestling, I have a feeling Mark here may be a fan of (or at least is aware of) a fighting game series called "Variable Geo". It's about waitresses doing fighting tournaments to promote their restaurants and because it's an ecchi, their clothes
will get destroyed. Worth pointing out that after the
first game of this series here:
...the franchise became outright porn, in which the losers are practically forced to do humiliation sex acts. And yes, it has lesbians.
There were OVAs both in the '90s and in 2004-2005 that were all released out here (the 2004 one is hentai). If anyone has ever heard of the series in the States, it was likely through the anime adaptations. His Debbi-chan persona, being obviously-90s inspired, kinda looks like she came out of the V.G. universe, which is why I immediately thought of it.
There's other wrestling/fighting tournament anime involving women that
for sure Mark is into, but not all of them are explicit like this one. In fact, despite my spit-balling here, the timing of the anime's release state-side matches with how long he's kept his female persona a secret for that I will not be shocked if
this was his fetish awakening.
