Wandering round the web (as you do) I came across this site.(link at bottom) Early days it seems, but some erotic audio on there, not sure how many are already in peoples collections but might be one to keep an eye on for new sounds....oooh Hot nurse Tamara again....
Search through categories to get to sounds, and note in some there is more than one page and the page selection is at the bottom of the page.
