Regarding the sexual sins that come up so often from mostly youth, I can vouch for the fact that in this over-sexualized world, Catholic youth are not being taught about the Church’s view on sex, virtue, love, etc. When I was in religious education, someone had asked about homosexuality and the teachers completely dodged the question. One section in my Confirmation program was about chastity and some of the questions that were in the book in front of us were avoided and not answered even though they were about masturbation, pre-marital sex, etc. That’s probably why there are so many questions.
People honestly don’t know and while I’m not condoning finding loopholes for that stuff, teens are curious and need real answers.
