What is prolactin?
Prolactin is an interesting neurotransmitter that gets its name from its ability to affect lactation levels in women. This neurotransmitter has over 300 uses in the body, but its effects on orgasm are well studied compared to other uses. An orgasm, whether physical or due to masturbation, results in the release of a large amount of prolactin in the body. It is this chemical that helps to improve mood after sexual activity, and can last for more than an hour. Prolactin and dopamine depend on each other for context and control during sexual activity. In men, prolactin directly affects the refractory period before they can maintain an erection and engage in sexual activity again. The older we get, the more prolactin is produced in men. Men with prolactin deficiency are often able to have sex several times in a very short time, or they do not lose their erection after reaching orgasm.
Excessive prolactin is usually associated with irritability, decreased testosterone and a significant loss of libido.
What is oxytocin?
Often called the "love drug," oxytocin is responsible for feelings of trust, connection, closeness and protection. A rush of oxytocin is produced during orgasm and is often attributed to the glow we feel after sexual activity. Oxytocin is released during all forms of intimate activity, including touching, hugging and caressing. After orgasm, in men, oxytocin levels drop rapidly until they are lower than they were before sexual activity, while in women they drop much more slowly, often remaining higher than they were initially. The reasons for this remain largely unclear, although there is speculation that it is related to ideas of empathy and is a necessary component of bonding, childbirth and childrearing, which also means that after orgasm, women are much more likely to let their guard down and fall in love.
Normal/high levels of oxytocin:
This is the love drug after all, and as such, high levels will lead to strong and powerful feelings of emotion, a sense of devotion and closeness, an increased sense of positivity, and feelings of protection and responsibility.
Low oxytocin levels:
Considers a reduction in feelings of attachment and connection, it is also responsible for low libido and depression, as well as reduced empathy for others.
How does this affect a man in chastity?
We just talked about how orgasm causes a substantial drop after orgasm in a man, with the drop in women occurring more slowly in the sense of a plateau effect. What if we were to avoid this sudden drop by removing it all? In detailed posts by Sarah Jameson on her blog on male chastity, she explains how after each orgasm, there would be a period of time when her partner, John, would not be as engaged in the sense of service and helping as he was before his orgasm. She timed this sensation to last between 7 and 10 days and used this tracking to extend the periods during which he remains in a chastity cage. If we transition John to sexual activity once or twice a week, which could be considered normal, then the levels of the neurotransmitters we just talked about would never really stabilize and as such, it would be a continuous roller coaster ride of emotions.
The most important thing to consider here would be the constant fluctuation in oxytocin levels that are responsible for John's mood, and his ability to engage in intimate activities with his wife through touching, caressing and other variations of it. For an individual who engages in chastity, or in John's case having multiple orgasms during a honeymoon like a weekend every few months, he will still feel the immediate downward spiral due to neurotransmitters and his mood will still change due to low dopamine levels and higher prolactin levels
