As anyone knows, its hard enough managing one account but to make another or manage three or four accounts!? Man you're outta your mind, anyone who watches you knows what you make; creating another account just to separate your art fetishes is asinine! Why make it harder for yourself when all you have to do here is make a different folder. If people want to see non-fetish artwork, they just go to that folder (or sub folders)... and if you want to feature a specific part of your gallery... there are widgets that are flexible and allow you to make that happen.
I wouldn't let peer-pressure sway my judgement too much, but if YOU want to add the extra work to your plate; by all means... go for it. It's just easier when everything is under one roof.
