Well i just got out of a relationship a while back with someone who was over 6ft and im 5'3. At first i was worried about the problems we wold have in the bedroom according to our height difference, but it turned out to be amazing! His penis was pretty average size too, nothing out of the ordinary.
I just met someone who is probably around 5'9". When i first felt his penis i was scared! It was bigger than i had ever experienced and i have been told that i am quite tight down there anyway so i worried a little bit as my ex filled me quite nicely but was nothing compared to this guy in size.
We decided to try it out, he went down on me to get me going and then he tried to enter. I was maybe a little tense so it was tough for him to do so. I could feel the 'squeeze', and it hurt maybe for a split second. Then after we got going it was really good. The feeling of him filling every part of me was pretty intense and i have decided i like this size alot
Maybe there is such thing as too big, but i think it would be more length than girth. Too long hits the cervix and that is really uncomfortable.
