The only thing I can think to add to this rather comprehensive list of suggestions and help is move slowly and don't inundate her with it.
From personal experience I have discovered the quickest way to sour potentially new territory is by getting eager from the beginning which can lead right into excessive in the other persons eyes.
Mention it, discuss trade, be very, very patient and work at the other persons rate of comfort, be prepared for stop periods where you have to back off and most of all, don't pressure. If your partner is very precariously toeing the line for you anyway, pressure, or any semblance of, will drive them permanently away and leave a sour taste in their mouth.
Also, be prepared to find yourself in a position whereby she might accept your taking part in them, she might be supportive and even encourage you to do 'as you like', she may not wish to participate and ask that you do it on 'your time'. If this is the case you will have to ask yourself if that will meet your needs and move on if it doesn't, because it rarely evolves positively from there (it can become a vicious cycle of pressure, whining, demands, sulking and attempts at coercion if you aren't feeling fulfilled).
