CD-i offered quite some 18+ content, something we would not always expect when thinking of the image of Philips and the education theme of CD-i. But most of the times, the Philips brand was not on it and as with more adult themed CD-i games (like Voyeur, Strip Poker Live) a different company took care of the publishing (in these cases: Interlance Publishing). We also have several CD-i titles that are about Tatjana Simic, showing nude pictures of her. Looking through the sales figures of CD-i we can see the logic in that: It sells very well. Anyway, Philips promoted some of them quite heavily, like 'Playboy's Complete Massage', licensing the Playboy brand and Valkieser also developed different CD-i's about the sex documentaries of Goedele Liekens (Loving for a Lifetime).
Interlance (who published Strip Poker Live for example on CD-i) also created the 'Women of the World' series, with at least one episode (I don't know any others): Brazilian Girls.
These were actually video-cd's, but well, at least these categorized in the same way as all Philips CD-i's, making use of the distribution channels of Philips Media. Many other, true porn video-cd's, obviously don't. So even in adult themed cd-i's, there's an educational value in it!
There are six massages on 'Playboy's Complete Massage', in full motion video. Very sensual, there's far less focusing on the documentary side like in the 'loving for a lifetime' titles. This might be a better choice if you're looking for this adult theme :) like in soft porn, breasts are allowed but no genitals are shown. It is still very suggestive and sensual. I'm surprised the name Philips Interactive Media is so clear on it, it seemed to me Philips was not keen to be printed on a sexually adult themed cd-i disc.
CD-i member Joey Tibbs shared with us a few scans of CD-i Magazine that were discussing some of these 'adult' CD-i titles:
