I haven't seen any Candida Royalle, but I'll second the Adam&Eve line of videos; well, some of them. Half are the "glossy" that you are looking for, half are standard. You can get good summaries at
rame.net: the home of civilized smut, which has links to reviews of adult videos. You can pretty quickly tell if it will be too much for your woman.
Personally, I would NOT recommend the Andrew Blake videos; they are so artsy that there is no passion or fun left.
And yes, the A&E videos will show penetration.
