I think you have to remember that JPII and others writing on this wrote more broad/generalized messages on catholi sexual morality so that it could face the test of time and still be applicable to new dilemmas we face in the future that we are unaware of now. People like West (who seems to have universal support by Bishops and Nihls Obst-so its says it is free from error) simply take those teachings and help to simplify it for us and also apply it for us. The bible is similar in that obviously Christ did not mention internet pirating or cpyright infringement, but we can take the command to do not steal and apply it.
I think for many, the problem may stem from hearing a more rigid type of teaching when younger that we hold very close to, so when we see West write something that may shock us, we can get very defensive and feel as if this person is out of touch with Catholic teachings. Well we have to remember that unfortunately some more prudish thoughts prevaded at times although not official teaching. Also, you will notice in his talks, West has refined them over time. (Note: When JPII came out with Love and Responsibility, that was very shocking- but right on).
Ultimately, these books have done a great job to help direct and spark the youth of the Church to embrace the moral teachings of the Church and a strong love for her. This will spark holy marriages, and religious vocations.
Yes, you may prefer other material because we all have personal preferences about style, but if it the teachings itself, I would say start with JPII’s TOB and then read West again. Maybe things will click.
