She's always been super faithful. Both of us have.

 What I was exploring wa how it made her feel when other guys hit on her and to find, maybe somewhere, encouragement that she liked it.

She didn't.

Eventually as we have grown as a married couple, she has even stopped noticing other men. I asked her about the event where a yong guy tried to sneak his boss out the door drunk. She was deeply shamed about it.

I changed tack by telling her how pretty she was and how hot she was. I've tried this many times, but a a bit of a hurtful past before my time convinced her she wasn't.

But this time I started to point out to her when other guys looked at her, especially when I was not visible or I was kind of farther away. I am a bit intimidating to see, so other guys tended not to even look at her in any event once I gave them a bit of a stare.

So now I actively did not. Instead, I tried to watch them.

And I pointed it out to her.

My teenage kids picked up on this, and thought we were helping with her self esteem, so when they went out alone with her they'd do the same. In fact, my daughters started to actively encourage her to dress more sexy (none of my accord but it was a stroke of genius).

At some point she was giving a talk to a group of cleaning ladies at work. All of them were black or immigrants. At some point once the formal conversation was done one mentioned how sexy she was shaped. And all of them chimed in to tell her that they would die for a body like that and that black guys in the office all had the fantasy of getting to THIS one boss lady. And now that they'd met her they could see why.

This coincidence played right into my hands as she mentioned it to me with some astonishment one night. 

I kind of played the "Duuuhhh... do you only see it now?" approach.

This got her thinking, so I decided to up the ante a little.

I told her that she needn't dress sexily outwards. She is was still way too negatively body conscious about her appearance, so I came up with the idea that she should wear sexy lingerie. I checked her sizes, went online, spent a small fortune on sexy lingerie and one night surprised her. I told her that she may be too body conscious in a negative way to wear sexy clothing, but she was sexy to me. So I had decided her and I would share a sexy secret. She would always wear sexy undies for me and it would be a little naughty secret she knew of but nobody else. I threw (almost) all the old lady underwear away.

She loved the idea.

I especially flattered her with frilly lace things, push up bras that showed her white cleavage off and tiny thongs that covered nothing. 

She demanded to keep some of the old panties "for period days" and I assented.

But the seed was sown... she now thought she was acting sexy by wearing sexy underclothes...

And men noticed that she acted different... and looked different...

She started mentioning it to me and I started to point out to her...

And then... I started using it... by telling her how it made me feel...

But enough for now.
