A logo for an adult themed email service

The site primarily focuses on email for the adult industry (ie gmail for porn). We have been kicking around xxx email xxx as a potential name or slogan or such. Interested in a logo that's fun to use and look at, that can potentially be a color scheme for the site so spin on into that direction. Somewhat abstract but not so completely abstract that it spins off into something else. plum purple, Microsoft blue or a Verizon red red are all good options for colors. Something that could make into being a permanent fixture on the site (ie: a swirl that then in turn blends into a larger swirl for the pages background, doesn't have to be that but something that could work as part of the pages's layout, color scheme, theme, etc). This is a very vague request I know but it's basically a "you decide" on this. I think a symbol (like the Pepsi symbol or Burger King logo) would be a good jumping off point. Not those specific I'm just saying a symbol in general (as opposed to a generic typped font) or maybe something like an illustration (like the KFC logo). Again not that specific logo just a jumping off point for the style of the logo. Thanks!!!
