Getting Comfortable...
Perhaps it's the job, but I think it's important to keep yourself attractive and healthy, both for yourself and your partner... that goes for the guys too. I'm not saying that you have to be perfect, but if my partner gained 100 pounds, I'll still love them, but that doesn't mean that I'd be attracted to them sexually. It takes work to have a successful relationship... in all aspects... emotionally and physically. I wouldn't be pleased with a man who was so comfortable that he completely let himself go and I wouldn't expect my SO to be okay with it either. As we age, our bodies change and that's to be expected, but I don't think it's an unreasonable request to want our SO's to stay health conscious if that's how you met and found attraction in one another in the first place.
