Viagra with the CB6Ks Cage

I ordered a CB6Ks that is arriving tomorrow. Its purpose it to prevent accidents during T&D and to permit my wife to not have to focus and concentrate so much when edging me to prevent me from having an orgasm. She wants to play with me and herself at the same time without worrying about my state. She needs to be touching me and hearing me moan to trigger her orgasms. The other reasons was to add a new element to our T&D play; erection control. T&D is our thing, and chastity is only part of it. She also asked me to get a prescription for Viagra which I have yes occasionally recreationally when facing a challenging evening. My concern is what the effect of having the CB6Ks will be? Can I harm myself? Will it split the cage if we keep doing it? Anyone else do this and have any advice? Is this a bad idea? A lot of us into fetish play know that sometimes the fantasy is much better than the reality and I would like to know if this is the case with Viagra and a cock cage?
