Since I gave birth, my husband and I had been having sex far less often.   I kept trying to initiate it, but he always found an excuse.   He'd say, "I'm too tired today. Tomorrow, okay?" Sometimes he'd tell me, "Our daughter just fell asleep. We'll wake her up." Or he'd say, "I just remembered some paperwork I haven't submitted. I need to get up and finish it." Then there was, "Keep a tally. I'll make it all up to you next time."   I was disappointed, but I also felt for him. He worked so hard to support our family.   Then I came across a post.   Is anyone else worn out every day because their boyfriend wants sex all the time?   The comments immediately blew up.   A: [Some of us are dying of thirst while others are drowning!]   B: [You're getting laid and you're still complaining? Regular sex is the best proof of loyalty.]   C: [I'm waiting for a boyfriend reveal. What does a guy with that kind of stamina look like?]   The poster immediately uploaded a photo of herself with her boyfriend, both their faces out of frame.   D: [He's got broad shoulders, a narrow waist, and an eight-pack.]   E: [I just sent this to my boyfriend. Apparently, working out keeps a man's engine running.]   I scoffed.   My husband had worked out for years, but he still couldn't perform in bed.   Then I noticed the diamond ring on the man's left hand. It was identical to my husband's.   It was custom-made. There couldn't possibly be another one anywhere in the world.   Suddenly, I understood.   My husband had no trouble in bed. He just didn't want to sleep with me.
