Hi Safi & everyone,
I guess I will tell my experience regarding retention.
The longest retention i had was 2 weeks in the recent times. I have an ankylosing spondylitis (similar to rheumatoid arthritis but occurs usually from young age), and this cause a setback for this retention practice. My body would be quite tense/twitchy which I think that the inflammation on my body was increasing. The most intense pain was my back which i had the most arthritis problem there. Another discomfort was that I wasn't able to concentrate and my thought process become convoluted. I am also doing a MCO everyday however, my meditation became too hard and unnatural during the longer days of retaining. Libido was greatly increased at day 5 onwards, however at around a week later i felt that my sex drive became stagnant. The reason for releasing was that my body became uncomfortable and painful that it was unproductive for work. I was also became extremely moody the longer I retained. I also have gastric issue, and for some reason it was also elevated during more retention.
After release, my inflammation was completely gone, and everything came back normal again. But i still want to do retention since I also felt the benefit from it such as I became more peaceful, more chi but felt some blockage. Too much ejaculation would also harm my body, as I feel quite weak, therefore I opt to never ever have any sexual thought in the future as when it comes it becomes uncontrollable. I am in the mid 20 btw.
Please give a feedback on what I should do for an easier retention process.
