Too far would be past first base, or second depending on one’s interpretation.

Sex is anything that involves penetration.

You only pass the point of no return when you know in your heart that you should have stopped and didn’t. Hard to answer that one effectively without knowing the details (which are personal to you).

Sin is when any action that you committed would be seen as such in the eyes of God. If you had premarital sex, but then married, that would be a moral issue; one that I believe would be forgiven. I believe God is very forgiving of any sin, if you are truly remorseful.

I am not a Rabbi or a priest or a minister. Don’t be afraid to ask one of the professionals. They won’t judge you.
