When the hubby gets a little chubby?

“I can’t do it anymore: have sex with my partner, that is. When we first got together 8 years ago he wasn’t a health nut or anything, but he was normal weight and very attractive to me. A few years into dating, he started to let himself go: eating too much and never getting any exercise. Three years ago when it became legal here in New Jersey, we had a civil union and since we’ve been married he’s gained probably another 50 pounds. Not only am I not attracted to him anymore but the sex has gone downhill too. He can’t get erections as easily, they don’t stay hard and he’s lazy about how we do it. It’s just not worth it to me anymore. I refuse to fake interest. If he doesn’t care about his appearance, what else can I do?”
