I understand that sexual intercourse outside of marriage is sinful. I’m not certain, though, what is entailed in “sexual intercourse”.
Is “oral sex” included in the category of what is sinful? How about pleasuring the other with one’s hands?
Is the grabbing of each other in ways that one wouldn’t do in public sinful?
In other words, what is sinful and not in terms of a guy and girl who “hook up”?
