yes it happens to be that way ...
but lets face it ..this is biz...people go into biz to make a profit .... if your in biz and you have an idea that would bring in the $$$ and it works why stop ?
As for why people spend $$$ for this kinda stuff i wouldnt know
but it sells ... and we are dealing with porn what ..what would offend You & I ...would get other people off.... that just the way th eporn biz is these days ..people are not really interested in quality anymore ...they are more interested in what sells..
