Good for you bro but I hear all the time after the wife gets a boob job her confidence raises, more men start paying attention and before you know it she's banging someone else. Just go into it with both eyes open.
That happened to my close friend. They were married for 15 years and then right after she got her implants it went down hill. A couple of the girls I work with got their tits done also. They get A LOT more attention now. Just a heads up.
