I am going to get everyone mad at me for this piece of advice, so take it accordingly.
You need to stop feeding the animals immediately. Backoff, and 180 on your desperation for her.
I know it is hard, but you have to shut off the 'needy vector' for a while. Evidently, she is convinced that your relationship is so one-sided, toward you, and that she is already doing you a favor by noticing you. You have likely helped her believe it.
Quit making her comfortable. Quit being Johnny-on-the-spot.
It is perfectly NORMAL to want to see your wife naked. It is perfectly human and it is OK. She obviously has a problem, either in her belief structure or because of some past issue. Regardless, it is her problem.
It is your problem as well, but because it is her problem.
If she needs to put down your looks and her level of attraction to you, and obviously on a continuing basis, then it sounds like she may be dealing with some serious security issues. If that is not the case, then why are you tagging along for the abuse?
There has been a good bit of discussion about respect here lately. Do a search and read those posts. From what you have written, your relationship is in dire need of some heartfelt respect.
All the best, -NOPkins-
I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
