Enhancing Husband

I’ve been with my husband for 14 years and married 11. He the sweetest man and I can’t imagine my life without him. Over the past couple of years we’ve both put on a little weight. I’ve gain about 20 and he’s gained 50-75. He’s 6’3” and over 250 now, I think he’s closer to 260. I’m trying really hard to lose weight and get into shape for our future babies. I’m having a hard time getting him on board. His sperm count came out fine so he says he doesn’t need to do anything to be healthier. I want us to be able to run and play with our kids. Plus, I think losing a little weight might help his stamina in the bedroom.

I feel like a terrible wife. I’m not saying he isn’t perfect. I don’t want him to be perfect but I want to make us better.

Please don’t be mean. How do I motivate him?
