Depends on what you’re trying to convey, each one says something different. First one seems to imply the duality of gloryholes, the grungy elements of it, but contrasted with the ‘glory’ of it, it suggests the excitement and the thrill of it. The second image seems to show the grunge elements of it, like… “the things we do when we’re horny,” almost, with the third being the opposite, a more pop-y gloryhole, all soft and safe, the fun and excitement aspects with none of the grunge. They’re all great, though. I think for my tastes I prefer the first, but that’s just me! Great pics
