I just got out of a 4 year relationship a couple months ago, and got on Hinge to test the waters. I met this girl who was a great person and very attractive, but also just got out of a 4 year relationship of her own. We met up for coffee and had an amazing time, staying far longer than the time we allotted. I then came over the day after and we had sex in her apartment, and this was the first time doing it since my ex girlfriend (who was my first). She and I both aren't trying to jump in any relationship and definitely want to keep it casual, but it feels really weird. Like I had the time of my life and it's really exciting, but I can't help but feel weird not being attached to the person I recently had sex with. For example, I love not feeling obligated to text her, but also it feels weird not doing so if that makes sense.
Basically it's the perfect situation for where I'm at, but definitely something I'm getting used to.
