I have some strong opinions on this, but I’ll try to be gentle.
Many Catholics would tell you that, even if you are being chaste, it opens the door to scandal and that’s a sin. They would say that it’s your duty to protect her honor. They would say that sleeping in the same room or living together prior to marriage is a sin, even without sexual activity, is a sin due to those two things.
My take on it is as follows:
- It’s nobody’s business what you two do together behind closed doors except you two and any person you bring into the fold by discussing it with be they religious in the Church, friends, family, etc. as well as God. If you aren’t in a position of leadership in which your actions could compromise your integrity or the strength of your message, it’s only the business of the parties involved and those they bring into the fold.
- Scandal shouldn’t occur unless you are announcing your practices publicly.
- Gossip is a sin. So anyone who encouraging scandal is just adding to their own list of sins.
So, if you are being chaste and not contributing to scandal, if you have the self control not to engage in lust or fornication, then do what you will. Share the same bed even. As long as you are being chaste, the only catechetical teachings that would prohibit it are those regarding scandal, your duty to protect her honor and contributing to the sins of others.
But, if you are a Chatty Cathy, your friends are gossips or you don’t think you can control yourself to be chaste, then maybe avoid the scenario.
You know you better than we do and God knows your heart whereas we don’t.
