I think the ultimate goal is to live without shame. I think all other problems one has stems from personal shame barring extreme life circumstances, which is something to be very thankful for in modern society. We look to love to absolve us of shame, we look to drugs to mask our shame, we look to accomplishments/physical qualities to compensate for our shame, etc. Once you learn to love yourself and expel your personal shame, thus being unaffected by other's words, you use see love, drugs, and accomplishments as bonuses or just for fun to your base self. Additionally, all the questions you struggle with right now also will either no longer matter or the answer will be readily apparent.

*Still good to know the truth about women, but ultimately a shameless person would be unaffected emotionally and would just see it as objective information to proceed forward. I don't think a shameless person would want to get married anyways unless they wanted kids as they don't have that need for unconditional love from others as they already have it for themselves.
