SEO friendly quality directories for adult content sites

[SkGold]

Does anybody have or know the list of SEO friendly quality directories that accept the adult content sites? I mean legal adult sites and not pornography.

So far I found 2 types directories for adult content:

1. General directories - some most popular general directories accept the adult content sites, however many of them have restrictions. For example: Gimpsy - accept the adult content however they show adult sites only for registered users. It means that the link to your site will be not SEs friendly.

2. Adult niche directories – probably the best choice, however 99.9% of such directories also accept pornography and that is question their quality.

It would be nice to find the third type directories that combine adult niche with quality of popular general directories.

So back to my question does anybody have or know the list of SEO friendly quality directories that accept the adult content sites?

Really appreciate your comments and suggestions.
