Morning wood is occasional, not a daily requirement, I don't pay attention to it. The penis is small and insignificant when inactive. Popular culture promotes the myth of the big dick, but it's all BS. It gets bigger and toned in an erection, otherwise it's small and soft, period. If you can have sex 3 times in a row, you are fine. Getting worked up about these matters is unnecessary in my opinion. But see what others say, I'm not an expert!
Rather, have you ever had psychotherapy? It pays to investigate the deep reasons why an addiction developed in the first place: sometimes is some kind of unresolved matter in your internal world. That certainly has nothing to do with the dick.
