Nice site, Allanah. The look and feel is awesome. I don't know how much feedback you want, but since I've been a web designer/developer for eight years and host a lot of sites myself (not in the adult sphere, though!), I'm going to offer some comments, some of which may be a tad technical, though I'll try to keep it non-tech. This first view is on Windows XP / IE 6.0 on broadband; I will take a look on Firefox and also on the Mac platform and see if I spot any cross-browser/cross-platform discrepancies.
I simply love the background images on each page; the site has so much personality and the backgrounds are very artistically done, yet seem to load quickly. I especially like the way the site represents you, with a lot of personal reflections and detail. The detail given to your transition is amazing; I don't think I've seen another site which has gone so far with this aspect.
I like the navigation, which is easy to follow. However, I don't particularly like the blue background overlaying the various colored backgrounds; on some pages I think the colors clash. These are set as images, swapping out on mouseover, and I think better effect would be achieved with html text and CSS, whereby you could swap the background color and the fontcolor differently against different backgrounds.
It also looks to me that the pages are hardcoded, rather than using SSI (server side include) files to populate common elements (such as the navigation bar); the pages are .html, not .php, .asp, or some other dynamic technology. Using include files would expedite updates to the pages, since you'd only have to edit the one include file that is shared across all the pages.
Regarding the links at the bottom: medical credits gains an underscore when you click through to that page (medcredits.html), but this doesn't happen on the surgical1.html page, and when you click through to FAQ, the links at the bottom disappear.
On preview4.html, the Preview, Tranny Life, and Tgirls Gone Wild images are incorrectly sized on mouseover, so the first two are way too big and the last is waaay too small (you can't even read it); looks like a simple case of changing the image width spec on these images). Also on the preview pages, the links don't work (e.g., the sample movies and photos); the sample images on preview1.html for instance refer to an image map, but the href (link) is set as # rather than a link (<area shape="rect" coords="6,18,82,124" href="#"> - should be something like href="someimage.jpg" or "someimageonapage.html"). If they aren't meant to link, then why have the imagemap at all?
Note on Wendy's comment: Gia's Store is hosted on the jojetstore.com site, so it is linking where it indicates, but I agree it's a bit confusing to look like you're on Gia's site. However, I recommend that, when you link offsite, you open a new window (target="_blank") so that people don't leave your site on linking.
OK, that's probably more than enough for now! I really like it, though I think there's room for improvement as noted. In fact, I'm going to have to sign up!
