I think pretty much everyone replying so far has me beat on states and Canadian provinces. For me, it it DC, VA, MD, NY, Ontario, and I think that is about it.
On countries, I have had carnal knowledge of ladies in a wider array of places, including the U.K., Switzerland, the Netherlands, Romania, Slovakia, South Africa, Thailand, China, Singapore, and France.
As far as country of origin of the women, I have been intimate with women from the U.S., Canada, the U.K., Argentina, El Salvador, Argentina, Guyana, Uruguay, Ethiopia, Congo, Lebanon, the U.K., France, Spain, Thailand, the Philippines, Singapore, China, Hong Kong, Taiwan, India, Japan, and I am sure that I am forgetting at least one or two.
At this point, I am pleasantly surprised with how wonderful women from all parts of the world are as lovers and gratified that I have had the chance to meet so many of them in such intimate circumstances.
