This depends on alot of things.Were the couples Christian?If not they are pretty much going to do what they want to do. I have heard of a Pastor who was very well known and respected in the Church have a moment of temptation and having a one time affair.and there are married men whom did that? I know a man who was charged with child porn(possession of videos) and caught by his wife and she turned him in and divorced him. I don't know if he did time or not. if he did it wasn't long because I saw him a year later.
im versed into that. but my disagreement is not with the control issue. but rather that you implied all rapists simply rape because of sex. not so.
