You select and solidify that you are a guy. You claim to be a masculine viewer, though the website doesn't ask for any of specifications beyond that. For all the website knows; you could be any weight, any age, any race, and any sexuality; a male blank sheet. You could also be some sort of sexual deviant, or simply innocently fascinated by the fantasy of watching (becoming) something new; a different species or creature. Though; someone like you probably didn't seek this website out simply for education or innocent curiosity, knowing from heresay how rather erotic the choices given at some points.
You are either nervous and reluctant, or devilish and horny as hell. Maybe both. Maybe neither.
In fact; as you browse through the list of species and scenarios once more, the site brings up a prompt to "name your scenario." There isn't any clear instruction on the naming criteria. You could title your scenario with your real name or a fake one (the website has a small disclaimer encouraging being anonymous), or title it related to what you hope to achieve in your created scenario.
Struck dumbfounded by all these options before you, another ping and pop-up shakes you out of your contemplating stupor reading that it is also "requesting your acknowledgement that you are over the age of 18" as well as one of those image and text puzzles to play and confirm you are not a bot. It happens to also have an extra disclaimer below that reminding visitors that all chosen and willing "participants" are also over the age of 18.
You breath a sigh of relief knowing this creepy tf fetish site at least has some moral standards...to an extent at least.
You click and agree to those terms and pass the bot test allowing you to finish up your scenario maker. And once again astound at all the options.
You are allowed to search for male and female participants, even giving you options on their size and figure; their color and sexuality, optional profession status. You can have the event happen during morning, day, or night; take place at their home, at work, in the woods, on the beach; etc. Some choices, like religion and age, are not available probably due to them potentially being the highest controversy.
You go through your selections and your options compile into a thread-like list, awaiting a name for this venture...and your clicking approval to move forward.
