Introductions discussion

Hello everyone I’m really fascinated by the practice of chastity. I’m single at the moment, but I’d like to understand how being locked up could impact a partnership and how a woman might react to holding that kind of authority. My guess is that I would pay closer attention to my partner in this scenario and generally behave better. I also enjoy the sensation of wearing a device. I’m wondering what Mistress Lucy’s favorite piece of equipment is and if she has any color preferences. My erect measurement is about 3.75” (I didn’t realize how small I was until recently, when a Domme explained that I’ve been measuring wrong – from the underside rather than on top, so I’m now accepting that 99% of men have larger penises and I belong to that less-than-4-inch group. I always assumed I was average. The Domme also suggested I look into SPH. I measure around 1.5” when flaccid, so I am looking for a device suitable for this size. I already purchased two devices – one is unused, and both are slightly too large.
