When Susan bought my first chastity device, I expected it to be a fun toy that I would be locked in for a day or so at a time when Susan was not around to assure that I kept my promises to not search the Internet and not masturbate. However, it did not take long for her to decide that I was to be kept under lock and key essentially 24/7 and she has kept that promise for a number of months now. Other than when it is off for cleaning, she only occasionally allows me to keep it off for special outings or while we are sleeping.
Overall, I have found it to be very uncomfortable to wear constantly. Because it creates a constant low level of irritation, I am constantly aware of its presence, which only serves to also make me aware of my genitals and sexual desires. I am also a bit paranoid that it will be visible to others through my trousers, especially in warmer weather when I am wearing thin slacks or shorts.
We have tried two different models. The first was a CB6000 Short, which was initially not very successful when I was overweight. Due to my small penis size it would easily slip off. We then bought an Exobelt V1 which is what I was wearing when Susan first decided I would be locked 24/7. It was very uncomfortable and bulky, but quite effective. It essentially provided a total shield for my penis and scrotum. Fortunately, once I lost a significant amount of weight, my exposed penis length increased sufficiently to where the CB600 Short is very effective. It is somewhat more comfortable, but I am still constantly aware of its presence.
Susan also occasionally uses our Ride-On Prosthetic Penis Extender (PPE) as a chastity device when we are home together. She bought it for extension properties, which made me feel quite inadequate. I have always been very sensitive about the size of my penis (about 3-4" when I am erect). However, she had always told me that size didn't matter that I fully satisfied her. But that stopped after she purchased the Ride-On to alleviate a problem I was having with premature ejaculation (which is only exacerbated by being kept in chastity). Due to my small length and girth when erect, it does not allow me to feel much stimulation during intercourse, making me last as long as she desires. She also found that she loved the deeper penetration it provided. So, now it gets used for two purposes -- to allow me to provide her with a longer and deeper experience, and as a chastity device when we are together in the house. She seems to love watching me walk around sporting a more normal sized penis. Unfortunately, that desire has also caused her to begin talking about wanting to by a soft packer for me to wear around the house or in my bathing suit.
I can't complain too much when Susan gets new ideas and wants to try things. I think I opened Pandora's box when she discovered my collection of photos and videos on my computer. She quickly took on the challenge of learning to spank me (which I love) and she periodically reviews my collection to see what types of things I found exciting. Chastity was one of my collections.
I have slowly learned that I should be careful what I wish for, and that reality is VERY different from fantasy. Many of my fantasies are not nearly as exciting as reality. Chastity is one of those.
