It's not just discomfort, but you need to work it like working out muscles. Starting light and moving up in weight or tension and time periods. Also there is the penile urinary tract that is the most toughest to stretch. If you start of in an advanced mood, you are only going to prolong the process and you will get unmotivated as you will not see the 2-3 month results. I started off 1week one 900g tension days 1-3 for 1 hour, days 4-6, 2 hours day 7, 3 hours. Week 2 I stayed at 3 hours for full 7 days at 1200g tension, then week 3 moved to 4-6 hours week 4 moved to 1900-2100g for 6-8 hours and been there since. I stretched 1/4 of an inch in 2 months and another 1/4 by month mid month 5. I have been using it off an on since as my work and business has gotten busy, but I am still seeing growth. Girth as been slight by about 1/4 of inch in the 5 months. I am expecting another 1/2 inch in month 9 - 12. But this is me, it's different for all.
