Taking A Break

... I am having a great time along the way. 😉

This is great to hear, the bliss of your here and now moments, this is the reward of being 'On the Journey'. It sounds like you have integrated your Aneros adventure smoothly into your daily life and are continuing the exploration of your erotic potential.
As to your question :"Can I last until day 21?" YES, you can, you already stated your abilities when you said : "I have already exceeded my previous attempts.", every positive effort is contributory to successful progress, keep attempting, keep progressing.
Good Vibes to You !

@rumel Thanks for the encouragement and a HUGE thanks for your countless words of wisdom throughout the Forum. There is so much to learn and many of us "newbies" would be stumbling around in the dark if it weren't for you and many other helpful people. 🙂

Have found that taking a break really enhances the next session in terms of increased feelings and arousal! Semen retention is not a problem for me as many times will go for several weeks before enjoying either hands free or sometimes resort to manual assist (try to avoid it whenever possible).

SR ended early on day 10. After a few hours of sleep I woke to a stiff erection and multiple dry orgasms. I thought I could ride it out but after two and a half hours I was exhausted and needed to get some rest. I stroked to a very satisfying T-O and was able to sleep a bit before getting ready for work. I am happy to get as far as I did. Now I am looking forward to an Aneros session in the next day or two.
