Always kept in the cage while she menstruates

I’d like to know if your keyholder behaves the same way as mine. I’ve noticed that any sympathy or freedom I get tends to vanish when she gets her monthly cycle. She has even confidently declared that since she is unavailable, there’s no reason for me not to be too. Part of it is likely because she isn’t in the mood and doesn’t feel like encouraging my advances, but I think she actually enjoys denying me during this period. Has anyone else had similar experiences?
