It's not like I'm disgusted by her is anything. She is still beautiful to me. I think it is just the reptilian part of my brain guiding me. When we (guys) see a healthy attractive female and we are healthy are instincts are to mate. That is what drove my desire to have sex before I think. I should make it a point to me more intimate. I started eating better and working out a month ago and I do feel more desire. Maybe it is the testosterone from working out. I think getting back into shape will help. I miss having sex for an hour or two. Recently it's more like 20 mins and it's felt what as I can only describe as mechanical. The exploration and intimacy isn't that good anymore, and we just need to work on it. Thanks for the advice.
