Broken?

When my husband and I first got together, I had no trouble at all getting multiple O's in a single session. But after about a year, I've started having trouble in that area. I don't know if I'm just not relaxed enough or if my mind is still thinking about other things even though I try to only focus on us. I feel like I have become broken since I cannot get an O. I have recently gone off my BC after almost 8 years because we have talked about TTC but aren't doing the BD a lot right now. Has anyone else had trouble in this area? If so, what did you do to fix it?
