David and goliath ..size difference

I just came across this topic and I have to say this has been a fetish of mine since I was a teenager looking at the 0 Holds Barred website. Being 5’11” and slim, any size difference taller and larger or even shorter and larger is a huge turn-on. If anyone has Skype and would like to talk more about this please message me privately!
 
Do you guys think that a taller man should be the taking a shorter man's ass and generally that is how it is?

I think the one who wants to get fucked gets fucked and the one who wants to top is the top. There are no rules it's all about desire/consent.
