I have spoken with a few couples over the years we have been living the chastity relationship and often come across the situation where things just 'petered' (no pun) out. Mostly driven by the sub male to include into the relationship, there is a significant requirement on the Female to craft the sustainability of chastity. Without this, the chastised ultimately becomes isolated in his own desires. Keeping the dynamic alive is a total commitment. Often the Female misses the fact that for the sub male, this is a real lifestyle choice, not just another sex game. Just my view, I'm sure its different for all, but for me as a dominant woman, inventiveness is key to maintaining the balance.
