No offense to twan...but stay the fuck away from any free hosting service. Get a domain name and a decent server, and use WordPress. Tons of themes out there that work great for adult blogs, or if you have the cash to spare, hit up
www.xlabor.com because they got some killer themes for under $50. Make sure to get the Google Sitemap plug-in...it got my (former) sites indexed in just a couple of weeks.
