90% of my sites are Joomla. Its wayyyyy more powerful then wordpress and all the basic stuff is point and click. Although it is helpful to understand php, mysql and html/css if you really want to deck your installs out or if you want something there isn't currently a pre made module or plugin for.
I would show you my pay sites with it but they are not up anymore but really you can make it look however you want. There is not set style for joomla (although there are popular templates floating around) you can literally make it look completely different then another joomla site if you know html and css and have your own graphics and if you don't... you can find someone to make a custom template for you pretty easily for not too much money.
Check it out but realize the general community is not very friendly to adult sites, at least in my experience... fyi
