[edging/bondage] My girlfriend (22) and I (F19) are wanting to try edging and light bondage

My girlfriend and I have been together for a while now and are very open sexually(meaning open to trying new things.) We both tend to switch roles regularly when it comes to who's dominant and who's submissive. But, I like to be submissive more than dominant and would like to try light bondage because I find it to be a huge turn on. When we had a conversation about it she agreed (she enjoys being the dominant one). I also mentioned edging which we have discussed before but have never tried. I wanted to try them both together and am here looking for advice for the both of us. This will be our first time trying edging and light bondage, so any advice is appreciated!
