My husbands double life

You said that "it's a little bit of a turn on for me". Admit it, you find his breeding to be a huge turn on. Your post isn't so much a confession, or even a plea for help. It's a brag. I don't blame you. You have held on to this very attractive male for 18 years, despite being lusted after by dozens of women. That took great skill as a wife and a lover. Go ahead, you deserve to brag.
I'll bet that every time he comes home with another victory, you become aroused. You find it exciting that another woman would be so attracted to him. A planned pregnancy is the greatest compliment a woman can give a man. As his wife, the compliment reflects on your desirability too. It feeds your ego, and a woman's ego is closely tied to her sexual arousal. Men get laid with compliments far more than with criticism. The conflict between your conscious opposition to his breeding and the enjoyable effect on your ego may cause you to get confused or lightheaded. I'll bet this is particularly true when he announces a new pregnancy. In this woozy state, you jump his bones, don't you?
And your arousal doesn't just last for a few hours, it comes and goes in waves. I suspect it lasts, on and off, for the duration of the pregnancy, maybe even a while beyond that. This is natural. It's your mind and body's way of keeping your Alpha Male providing for you, not this new slut or her hungry child. Your desire, conscious or subconscious, is to keep his seed flowing your way, reinforcing the bond you have with each other.
His continual breeding is most likely the basis for your "wonderful sex life". Criticize him if you must, but appreciate and enjoy the ride. It's ironic that fathering kids outside your marriage improves sex within it.
BTW, your kids will find out eventually with 23 and Me. Better they hear it from you two.
One question, what traits does your husband have that women find so attractive? Obviously, he has a strong sex drive, but there must be something more.

This is one of my biggest fantasies. Does your husband tell u all about it afterward?

This my absolute biggest turn on as well. Can’t get enough of it. Wish there was a way to contact the stud in question because I’d like to hear from him regarding some his stories and which was the most memorable. He’s my idol.

Well I know a lot of stories I can tell you. The most memorable was probably in 2010 when my husband and I ran into one of his 'conquests' in a shopping centre, with the child in tow. I had no idea why this woman was marching towards us, then clicked on when my husband whispered fuck. She said your husband did this, that and the other. I was looking at the little boy, he was at a guess, 3 years old, my husbands piercing blue eyes. He looked just like our oldest boy, no denying it. I looked at her and said 'you may have slept with him but he's not the father, my husband had a vasectomy back in the 90s' she bought it, I mean why would I lie? I was furious with him though, I've never wanted to see, so to speak. The child looked well and smart though.

I for one thing you're a top wife.

Omfg I just heard about you on another post. Wow how could You?

He's never hid anything from me it's all out in the open. We have a wonderful sex life, it bothered me a bit in the beginning, but it's been so long Now, it's a little bit of a turn on for me when he comes home and tells me 'the deed is done' I know he does not love these girls, soon as it's done he never calls them back, he's just gone. I'd be mortified if our children found out. He's getting on a bit Now, maybe he'll slow down.

This is so sexy

24 children!!!!
