Your index.html

You need a site title top of the page, maybe with some graphix to reassure the surfer he's at a site with porn.

I would make the enter link bigger than the exit link.

Separate boring text from your sales pitch. E.g. your terms of use text, which isn't necessary. I'd just not use it or put a small link on the bottom of page. You have copyright text, terms of use text, warning text and by the time a surfers' done reading that he won't bother reading "fashion & glamour" text.

Use small font for text you're not using toward making a sale. If possible, remove them, except the warning text.

"100% ...of 100%" text could be juiced up.

Main.html

You need more text on the page. Get the visitor horny. Talk directly to the visitor (or pretend you're talking to yourself) and establish trust/authority. Talk in detail about what the surfer will find at your site.

Gallery.html

You only have 2 links here. Add another link. Again more text.
