I have no doubt there are many other people who see sex this way. I'm a woman, and as far as I'm concerned, as long as all parties are consenting, I have no issue. Those who believe that all people should feel the same way about all things have a very blinkered attitude to life.
Having said that, I hope that your wife is OK with your choices. Like it or not, she's an involved party here and her consent is important. I'd hate to think you've placed her in a position of harms way without her consent.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
