Since this is in "non-fiction".
Perhaps a minority of wives/gfs might eventually become turned on and thank you for the sexy surprise, even if this was done without their prior consent. Perhaps a higher proportion than the porn fantasy where a wife/gf walks in on a man screwing someone else and then joins in for a full-on threesome ... If you have such a wife/gf then you are very lucky!
In most cases I suspect that she will feel that you have betrayed her trust and feel violated - due to lack of consent - "yes means yes and no means no". Split-up, divorce? Police called? as this is a criminal offence in many places.
I sometimes wonder about the requests in General Discussion, Site Feedback and Support

for "Delete accounts and all posts"
When I have lost interest in a forum I have registered on, I just stop visiting - I don't ask for my posts to be deleted as these people do.
How many deletions are because the wife/gf finds out and objects to her pictures being uploaded without her consent? or is it a probation officer's order or defence lawyer's suggestion? or religious conversion? Or something else? The Leavers aren't here to ask.
