First off, congrats for detaching! It is a relief and a peaceful state of being. So, good on you!!
Yes, I would confirm not to jump to any conclusions - which you clearly haven't. I like Chatterbug's suggestion to just pick it up and put it together with the post.
As you say, give it a week or two and hopefully she will mention it herself. Maybe it is self-pleasuring she has in mind, and could be to your advantage.
Now, I just want to also add that maybe she is sending those things to get a reaction from you somehow. If sex has been sporadic, it could be a message to you. It's clearly not something she wants to hide, but rather be more suggestive in some way. The only thing is that we are not sure what way that is.
