The only reason I would "wish" I could want kids is because I know my husband would have liked them (or at least one). For us, the subject of kids didn't really come up until he asked me to marry him (we were only 20, both still in school). I told him he shouldn't marry me if he wants kids, or expect that he will change my mind about it. He married me anyway, claiming he wanted me more than kids. We've been happily married 7 years, and that marriage has survived 2 accidental pregnancies (both were terminated, obviously) and my having my tubes tied. We still openly communicate about it, and the last discussion we had about he admitted that he enjoys the trade-offs of not having kids, but he still always pictured himself as a Dad. And, he still claims that he'd rather have me:)
So, yeah, I wish I could want them for him. He gives me everything I could ever want and even more, and I wish I could do the same. But, I can't, and he never makes me feel bad about it. He just loves me.
There's hope. Maybe you won't find a guy who doesn't want kids, but maybe you'll find someone who wants you more (and also enjoys sleeping in on the weekends:) ).
