I never thought I would hear myself say this, but I too didn't like the swearing in the Longest Journey. It felt gratuitous and unjustified. Does she say it when when she sinks the boat? Perhaps there it was justified and even funny.
I don't particularly want sex scenes either in adventures but I don't regret the one sex scene in the uncut version of Culpa Innata. As it was a nightmare and we were meant to feel discomforted by it, just like Phoenix was when she woke up. I would not have minded a sex scene between Phoenix and Jean-Michel though. Hard to say, I guess it depends on the adventure and circumstances, and in Culpa Innata it was justified, their whole social society is based on one night stands.
But I would not have found it appropriate for April Ryan or Zoë Castillo to have a sex scene in the Longest Journey. But I did enjoy the romantic scene of Zoë with that guy in Japan in Dreamfall.
And the scene when Gabriel Knight jumped into bed with Grace in GK3 was well done.
What I like though are sexy characters, I see nothing wrong with that and I enjoy it. As long as it is not too obvious and that it is done with taste. It must also be balanced, if a girl is sexy, well the guy should be too, otherwise I feel something is not right.
As for Phantasmagoria a puzzle of flesh, my mental state after playing that incredible game was more worrying to me than any sex scene or innuendo which I can't even remember. Which reminds me, I must play that powerful game again...
