It's axiomatic that dread facilitates an LTR's respect and desire. However, flaunting your interactions with other women, particularly to the point of overt touching and flirting is counterproductive and insulting. A faithful LTR, assuming that cryptozoological creature exists, deserves a modicum of respect.

I am 51 years old and my wife is 50. We have been married for over 30 years and have been a couple for 34 years. I have always lifted and kept my self in decent shape, and, as a result, so has she. I have never had to even encourage her to watch her diet and workout. When I was 17, I would go to the gym and soon she was right beside me. Even as a teen, she witnessed the attention that the gym gals gave me and responded to the subtle competition they represented.

I have been a teacher for the past 25 years and she knows that most of my colleagues are females, many of whom are well educated ... a few are even attractive. I am certain that those women have inspired my wife to be well-read and to be the hottest bitch at the faculty Christmas party.

Though my wife has always had a high sex drive I expect her penchant for fellatio is, at least partly, an intuitive response to an unspoken challenge.

In recent years, as a hobby and to help convince myself that I'm still a badass, though an antiquated one, I have taken a part-time job as a bouncer in a pretty rough bar/club. The servers there are young, cute, and slutty 20 somethings. She often visits me at the job and sees the young thots touching me and though I am friendly with them, I never go out of the way to take part in the constant game of grab-ass that takes place among security and servers.

This recent job/hobby has made my wife even more affectionate. It is almost as if the competition makes her moist.

TL/DR You can dread without being a douche.
