I have. I prefer it with someone else, but it's hard to find women who want to do it to you. I'm not super into guys so I only do it every now and then. I usually end up cutting myself, which is the most fun I can have on my own, but at the same time I can only really reserve it for once a week at most to make sure I don't go too far. A good rule of thumb I use is to not do anything until the batch of cuts from before is done scabbing and has turned into scars.
I'm so jealous of these two, I have all the pictures saved that the artist has done of them.
