[Hish]

Sounds like you two are struggling with temptation by wanting to act on feelings. It’s only human to have those feelings but to act on it before marriage is a sin. Yes, having sex before marriage (fornication) is a sin. God's will can overcome any temptation. If you feel you have the strength alone to conquer any temptation, you are setting yourself up for trouble. Man is known for falling into sin, especially when there is overconfidence in the self. Keep your eyes on God, and allow God to help set boundaries so you can resist the temptation. The Bible is full of helpful advice when it comes to coping with temptation, and it can be a useful tool.
