For the most part - I would tend to avoid meeting females on line. Generally, they are not physically up to par. I have been modeming since about 1986 or so and it is not too often that I would meet any hot girls on line.
Except, for these sisters I dated about 5 or 6 years ago. The older one was a modern dancer going to college in Davis, CA. I broke up with her and dated her sister after she got out of high school and became legal. That was cool. But, that was a very rare thing. Most of the girls I have met online look like nose tackles for some pro football team. There are exceptions, especially now with more and more people going online. But, you never really know until that fatal moment when you decide to actually meet them somewhere.
My roommate started talking to a female unit off in Iowa or Idaho - one of those farming states. Eventually, she flew out to California to meet him. Now, I had heard her voice one time in a voice mail she left him and I guessed she would be.. plus sized. And, lo and behold, indeed she was a stout woman. Not as if he minded.. apparently, he likes women with "junk in the trunk". But, it just goes to show that attractive women on line are a rare and treasured commodity.
