As for anal, my head is smaller than my shaft. It funnels in sweetly, and I’ve never hurt a woman on anal sex. I also know what I’m doing.
Sorry to burst your bubble I am with the larger group of what is listed above and I still stand by what I seen as reasonable in the first post. I don’t know what type of women you are dealing with in Brazil but from my experience most of them are to tight to enjoy anything close to what you are claiming. Been to Rio a few times ;-) and I am referring to the street hookers that do this day in and day out to eat some being stretched out by three children and such. 6.5” is most likely to much for a normal woman to withstand and if you think you are getting that in her ass without discomfort or bleeding you are kidding yourself. What you think is average is starting to enter the 1%-5% percentile of men. Not that many are walking around with 6+ inches. My base is 6.25, mid shaft 6-6.1 and upper shaft 5.7-5.9 and this has caused enough eyes to roll in the back of the females head for me to realize it is enough or more than enough but like yourself I am trying for more but not to the point where I start being denied anal sex because of my self motivation
