In my beginning called a nice gal who'd visited me as a pro; she also did web design and made me a basic format/template i used for years with adult and mainstream projects.
Also did an adult site on blogspot which got up to 1mil pvs/mo until google ruined blogspot. More recently, an adult wp site with a simple template. The words and images are more important than the theme.
