Chastity and cuckolding isn't a barrier to intimacy, but builds upon it. Taking your cock out of the equation and allowing her to fulfill desires with others builds your desire for Her, and ache to serve Her and by extension her bulls. Service and obedience leads to intimacy

In fact, the cock can be a barrier to intimacy. I've been around the sun enough times to know PIV sex is ultimately selfish on my needs. Even on my best days, the satisfaction she gets from it is very short lived. The hormone purge after an orgasm stops intimacy in its tracks.

And, if you're honest with yourself, you know it. You know after an orgasm, your body just wants to shut it down. Your ache to kiss her, hold her, and eat her out isn't nearly as strong after an orgasm, if it's even still there.
