Hello! My opinion is that the categories indeed need to be reviewed and, if possible, reformulated.
Since this is a website that revolves around male gear—it is not, for example, a platform to simply show off nudity or erotic art—I think there should be several broad categories organized according to the type of gear: thongs, G-strings, Speedos, singlets, jockstraps, unitards, etc.
Right now, the categories do not seem entirely consistent, as they mix things of a very different nature—for example, a brand such as Koala alongside categories such as bareback or dildo. One classification could be based on the type of gear; another on the material or textile; another on the model's body type or physical features, and so on. These categories could also overlap and cross-reference each other.
If we want to maintain the specificity and, in a way, the exclusiveness of the website, there should also be a filter to discard or not allow pictures and videos that have absolutely nothing to do with the site's theme. It is a platform to celebrate and showcase male assets in gear; it is not simply a page for posting nude material. There are many other websites for that.
Depending on which physical features the model intends to accentuate, another classification could highlight, for example, oversized bulges, prominent pecs, thick legs, and so on. Naturally, the same content could fall under several different categories.
Ideally, the gear should remain predominantly Spandex, since that is part of the website's essence. It is true that becoming too strict with the categories could constrain the universe of users and subscribers. At the same time, there needs to be some logical and coherent criteria for classifying the content; otherwise, the website risks losing the original spirit behind its creation.
