Hung, hard, bottom advice on chastity

Hi!

Just the idea of getting locked gets me incredibly hard. However, I am pretty hung, and when bottoming, I get really hard and easily cum hands-free. I fancy the idea of trying to lock myself, and even trying to bottom. However, as I mention, I get really hard. Does anyone have a similar experience? Once caged, do you stay soft? Just the thought of getting caged feels painful to me. My idea would perhaps be to just stay locked for a while before sex, or If I dare and manage to stay soft, while bottoming. Thanks for any insights!
