Over the many years I've being sexually active (45 years) I've seen and had my fair share of sizes.
In my working environment I've had the micro penis and I've had the 10" etc but the largest I ever had was in my private life. Was one of my college lecturers and he had 12" and all I can say is, I'd rather have average. I'm not tall but I've got a short vag channel so he didn't go down well but I did pass all my exams that year rofl.
Last year in work I had a nice doctor from Australia, visit me while holidaying back in Scotland. Ended up he had worked at the hospital I had my children in AT THE VERY SAME TIME ... Was spooky. Anyway, this doc didn't have a long shaft but when it came to his bell end, it was like the size of a cricket ball, I almost died when he took his boxers off. I thought I'd never be able to take it, but I did, but I wouldn't like to be doing it every week.
We just got to learn to work with what we have, some are not as easy as others but we can try.
