When we were watching IR porn, husband would ejaculate almost without using hands. We were then considering options on how to prevent him to cum so easily and he then started using a cock cage, first only when we were watching porn. Later, he's also being using the cage during my encounters with black men where he was allowed to watch and, recently, participate in an assistant capacity. Only last week, he wore the cage for 5 days consecutively, not without problems.
I feel, and told him too, he is more focused on his work and on my needs. We are looking at changing his cage to avoid physical problems. He would wear his cage permanently and I would only remove it for having sex with me and when I see fit.
