Hey, a Christian that has read the Qur'an (even the deleted sections) here.
Abba, our Father, believes s*x is a beautiful thing because it conjoins man and woman in the flesh. It is a sacred convent. (Genesis 2:24) Which is why when you do so, you must be married and deeply in love with your partner. You must have a commitment to them and a steady, pure relationship with them as well. They should be your only s*xual partner. (Corinthians 7:2 condemns multiple husbands or wives, meanwhile in the Qur'an, polygamic relationships/ multiple s*xual partners is/are heavily practiced. Mohammed had slaves for pleasures, so too should be allowed in Islam.)
When talking about any lustful desires before marriage, this is where Mathew 5:28 comes in:
But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.
This verse of the Bible is to say that do not keep secret sin because God knows already. He sees all. Even if you have not committed the act, you have kept it in your heart as that.
Look: love before marriage is fine. You will have lustful thoughts. In fact, we've all had lustful thoughts! Everyone. Even me. I don't know if romance is Haram according to Islam, but as a Christian, romance is a beautiful thing that forms a bond between a man and a woman. S*x before marriage is a way to gratify your flesh alone (Romans 13:13-14). And onto dating, I believe that us, as woman, should be a wife when we start dating/getting into a relationship (vice versa for guys). Don't ever have a "girlfriend" mindset. So many people get into a relationship and immediately go to pleasure - then, as time (weeks, months, years, decades) go on, you break up because the only thing holding the relationship together was pleasures. A waste of time, energy, and unfortunately, people never learn from that. So even if you're not spiritual or religious, you have to agree that it is a waste to spend your time with someone that isn't willing to commit.
1. I think kissing is okay, but nothing like making out and/or groping because that can lead to thoughts and thoughts can lead to actions.
2. Romance movies I believe is also okay. As long as it's a proper relationship being displayed, it's totally fine.
3. Parents that shelter their children will get the bite in the end. Make your child strong in faith and not able to fault at a kiss or a romance movie. That is the goal. Strict parents that shelter often have their child rebel. (Rebellion we got from Adam, which passed to all.)
I think it's important for kids to know this stuff. Or shall I say pre teens. It's very important that they learn and understand what is right and wrong instead of be sheltered from the wrong.
This is long!
