Newbie Needs Help

I’m just starting out with the PE program. I’ve read through the newbie guide and I too went and bought the penis pump. Your mention you had a small penis when you started. Anyone that started with a small penis and had success please give some advise. If you already had an average or big penis it’s not going to help me much. I’m 44 and have made a conscious decision to get bigger. I’m 7cm flaccid and my penis girth is small so being a big man it’s like this micro penis. Always embarrassed about its appearance. Erect I’m not big either. 12cm and 12.1cm girth. Erect wasn’t such an issue because few people saw the erect penis. My short term goal is to get my flaccid penis to get bigger.. Look bigger and volume increase. I started with the newbie exercises and found that I really have a hard time doing the exercises because my flaccid state was just too small. Also I found that I had some discomfort sometimes even pain because the internal penis wasn’t working with especially with the stretching. It feels like there is a rod or cord like stopping the stretch and this is where the pain originates. Even with the warming up. Anyone that had a small penis mainly flaccid and had success.. I would love some guidance to overcome this.
