Well, you are already had an opportunity to prepare to go in that direction, if went to the extra photoshooting, did it, and did the "right" choices. The trick was that if I remember well it "interfered" with the event at the gym, and that would have also potential consequence on the event at the beach, and the possibility of further events at the gym.
Notice though that Zorlun indicated the game will not be finished before the end of the year (if I remember correctly, actually, a bit in the new year), which means, it may still be possible that he somehow "goes back" and allow to have both something (more/further, for the ones that had it alread) at the gym, and Myriam starting to explore more daring photos and eventually videos, probably also depending on what she has done with her social network account (though in itself, that does not mean, she could always do kind of "private videos" or webcamming, even without becoming a full blown pornstar, and Marc itself had mentioned the idea of making money with pictures and/or videos (if she is his "fun whore" or "sub") or he could already use the pictures he took in the next update with his teammates, or take a video and/or other pictures there (even if he does the stuff, if she is "fun whore" or "sub") .
