As I understand it, Google asks that you submit all versions of the adult site in WMT (I don’t mean a sitemap, just have the accounts listed in there) but you only need to worry about your preferred version; in this case the https.
For example, you can have:
http:// www. yoursite
http:// yoursite
https:// yoursite
But the last one is the only one we ever check for anything as it’s the preferred domain. This is the only one you need to submit any sitemap for, or check robots.txt and so on.
