personally not really a big fan..

flash has some really cool purposes though.. I mean on movie sites, game sites stuff like that.. But on a porn site I don't think so.. You can get away with just as an effective effect using HTML and graphics that will load faster and be less CPU intensive on older computers.

its all about holding their attention for the 2-3 seconds they are going to be looking at your page and if 1-2 seconds is for loading flash then I don't see how it is worth it
