TTC BD rant!

I just wanted to whine for a moment. Sex in my relationship has always been great. Even before ttc, we usually did it every day. Yesterday was an important (higher chance) day for us to do it. He went for so long, and I had wanted to kind of get it done and go on with the things I needed to do. I mean, do you really want to have sex all day? We've been together for 5 years! Anyways, he could tell I just wanted him to finish and it totally ruined the mood. He didn't finish, and for the first time ever, I walked away thinking that it was a waste of time. I don't ever want to view our sex as a chore... but I'm afraid that as our ttc journey continues, I'm going to start feeling that way.
