What you don't know DOES hurt you. Having a wife that goes behind your back and shuts doors that may be opportunities for you, or makes it harder for you to move socially, you can feel that and it tears up your confidence. It hurt you, and you weren't sure why that was happening.
A wife that cvcks you, but makes up a excuse that she has severe ovary bruising and "cannot have sex", 3,6,9,12 months go by, no sex, no affection, no sexual attention. However another guy outside of the house is having her kiss his azz and make all his sexual fantacies come true. You don't know why but you feel "diminished" from before when you guys had sex, your dyck doesn't get all the way hard, maybe 80%, and it takes an effort for that to happen. You are not sure why, and you blame it on aging or stress. When the problem is very simple.
The poker table that your wife represents has another guy setting at it. Your wife is the house. She's taking your money and making you lose artificially EACH and every time,, and she's giving all the "stuff" to the other guy. Your "stuff" decreases, his "stuff" is supercharged. And you don't know exactly why but you can feel it. What you don't know DID hurt you.
