Being HD is not extremely vulnerable unless you are sharing intimate details about how desire and sexuality affect you as a human. Unless, you are owning your sexuality and not using it to blame her.
Being HD can also be used as a shield. You can use sexuality to deflect your parnter from getting to know you. You can use sexuality to shame your partner.
You have yet to really share specifics about your W, your R, your situation or your efforts at talking to her or improving things. Cemar, at this point I think you use your HD as a method to show that you are "right" and she is "wrong" because "everyone" knows that sex is an important part of marriage. Yes it is and it isn't the only part. Quit using your sexuality as a shield for your own fears and inadequacies. Quit honing in on her fears and inadequacies.
