Save your sexual life for marriage.
All of it.
Most people I know, didn’t. And they all regret it.
I also know a few who did wait. None of them wish they hadn’t.
Anything past a kiss, is an intimacy that should only be shared with your spouse.
There can be many physical and psychological consequences to not saving it for your spouse.
2 Timothy 2:22:
So flee youthful passions and pursue righteousness, faith, love, and peace, along with those who call on the Lord from a pure heart.
 1 Corinthians 6:18-20:
Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s.
I love you.
