I would just make one observation about a possible sex chat you are planning. Don't come across as being a lost boy looking for her to dictate/decide everything. I know this is not where you are coming from but IMO if you come across as too unsure, that is unattractive. Women don't like having to decide everything and like their man to be decisive and self-confident. Whereas I believe it is fundamental to be interested and respectful of what she wants, be careful not to come across as sheepish.
Maybe just let her know that in the future when you initiate, there is no pressure or obligation for her to respond favourably. Only you can read the situation, but I fear it could still be a little soon to fully outline your wants. Again depending on how your conversation goes, I propbably would wait a little before letting her know you would like her to initiate. However if she does so in the meantime, be sure to acknowledge it positively
Got to go
best wishes
