I think that's most likely what'll happen. I didn't expect there to be any mention of actual sex (or in this case, rape) in the comic - if they were okay with being obvious about it, there wouldn't have been the sinking behind the table moment in the first place - it would have been all out in the open.
Likelihood is that the scene was written vaguely enough that it was up to the audience to decide, and in this case they did decide and they decided it was rape, so, understandably for the writer and Marvel themselves, there's a lot of hand waving and "whoah, we never showed them having sex, so they never did."
If they do explicitly state that they never had sex, then I can't quite see the logic in the scene in the first place. There's not a lot of humor to be found in the making the readers think she was raped.
