My girlfriend and and I started dating in college, years ago. We had a fun, if vanilla, sex life. The most daring thing that happened was that I bought her her first few thongs. She knew I liked it when she wore them during sex, so she would do that. The sex was frequent and enthusiastic, and I was happy. I graduated, and she still had a few years left. Since I was living a plane ride away, she brought up an open relationship, and I agreed. I had some fun during the open relationship, but that’s another story. Our open relationship had a few ground rules: use protection, don’t get emotionally attached, and a general “don’t ask, don’t tell” when it comes to hook up details, as she didn’t want to he about what I was up to. We talked a lot about feelings, reassured each other we still loved each other, talked on the phone all the time, had some phone sex, etc. I didn’t think very much about the open relationship at all; it was just a normal distance relationship.
