This week I ended my 3 month chastity/semen retention period, with a coulple of orgasms. The first had an anal content - a first for me - but I found the the anal stimulation needed was rather too fast, and at that time I needed a more gentle 'screw'! The second orgasm, soon after, was more traditional.
A few hours later, I felt really great, and thought that the 3-month period was too long for me. Two weeks would be enough. It was interesting, got me into some new areas, but I will not be going so long again.
