I absolutely agree with the last comment from "magicdick" (9/2/2024).
I'm a bisexual married (to a great woman) guy who has an undeniable feminine/SISSY side, a total bottom who's sexually submissive with men, a DL (Diaper Lover) for most of my life, and with my wife/Mommy's help and encouragement also realized I also have AB (Adult Baby) desires/tendencies. I'm also a cuckold. Yes, my wife has a boyfriend who's also her highschool sweetheart, and I couldn't be happier about it.
There's a reason I'm her husband, and he's her boyfriend. Her and I share a VERY SPECIAL and unique connection (both emotional and physical) that her boyfriend could NEVER replicate or replace. I'm also the more gentle, caring and attentive lover in bed. Sure, when she wants/needs a BIGGER and THICKER cock (he's 8"c and really THICK to my 7"c and fairly thick"), along with the rough, aggressive, animalistic sex that I could only dream of giving her, HE'S her man for satisfying/fulfilling those desires. Other than really good (great?) sex and good friendship, he doesn't really bring a lot to the table.
For reference, my wife has known him for 26 years, they dated all through highschool, and they've been girlfriend and boyfriend for the last 6 years.
Her and I have been together for 18 years and married 16 years now. Believe me when I say my wife's boyfriend poses no threat to my marriage, and it's a very good, beneficial arrangement for me, my wife/Mommy and her boyfriend.
