Teasing and denial is much more potent and sexy when it’s infused with variety. Some people I talk with online are locked up constantly, only to get an orgasm occasionally, then go right back into the cock cage. For me, that approach would lose its appeal pretty quickly. It would suppress the libido, which in my opinion is the opposite of what t&d is about.
I liken it to being outside on a hot day. If you’re outside all day, you eventually get used to the heat. But if you’re going back and forth from the air-conditioned house, to the heat outside, then back in, back out, the heat is much more noticeable. Same way with t&d. If the sub knows exactly what he’s missing, it only makes him long for it even more when he doesn’t have it. If it’s static, unchanging, you get (more or less) used to it. When you rarely have orgasms, you stop missing them since you hardly remember what they were like. You get used to chastity. If you throw some variety in there though, it has a much more powerful effect. For example, instead of one monthly orgasm, why not go for a month of t&d, then be free for a week or two, locked up for one week, out for one orgasm, locked for two months, out for a few days, locked for a couple weeks, etc. Mix it up.
To me, not knowing when my release will be adds to the thrill factor. It could be today, it could be over a month from now. This keeps the anticipation high. Knowing that I’m at the mercy of the one holding the key is soooo much hotter than going by a schedule or point system. And it’s much simpler.
In regard to the one-orgasm-a-month approach, having one orgasm isn’t enough for some, especially if they’re multi-orgasmic. (Yes, men can have multiples. I highly recommend this book if you want to learn how.) While it can be hot to occasionally be locked back up without full relief, doing it regularly only serves to deflate the sex drive. And isn’t t&d about increasing the sex drive rather than suppressing it, bringing the sub’s desire to a height they’d normally not achieve on their own? This desperate hornification can be more easily attained if the sub periodically gets the opportunity for full relief, the total freedom to have orgasm after orgasm. Then, when he gets locked back up, it’s much more of a torment since he’s had a full taste of what he’s being denied. He knows exactly what he’s missing, and it increases the intensity of the denial.
