I have small hands , but quite a big ding dong . Bigger than average at leastRead somewhere a while back that your erect penis should be the length from the base of your palm to the tip of your middle finger.
dunno , from my experience they are ok with banging them , but it does not mean that they will also enjoy it. Especially if you go deep and fast
if you go slower , then yes , they will not feel discomfort . But it will be not that enjoyable for you
7+ inch I think it is in the very big range
if you look at porn movies with black dudes , you will notice that it does not fits most of the time more than 3\4 of the penis in the woman
