I've never done internet dating. Only long distance or internet type thing I ever had was, in short terms because this tale would take a long time to tell, the source of more joy and pain in my life at the time than anything else. It made me convert to another religion, cause friction with my family and, the good part, sent me through a road trip in pre-9/11 US that had me end up in several states. Ironically, when I came back, made my relationship with my folks stronger. Also realized how ridiculous established religious dogma was ;-)
I mostly base any type of dating I do on a healthy mixture of looks and personality. Looks are what "reel you in", the first thing that catches your eye, that wants to make you know the person. The personality is the reason you stay. My "type", I guess you could say, is stereotypical of guys; I like generous proportions, smaller girls and nice legs, physically. However, looking at my previous relationships, there is maybe ONE girl that fits that actual type. I've dated girls that outweighed me by 100 pounds ;-) I've dated one for two years who was so thin I thought she'd break and even I had more breasts than she had LOL. However, all of them were special and it's their personalities that kept me there, much more than the physical aspect.
Also, there ain't nothing I hate more than a cute girl who's the evil queen of number, who thinks too much of herself and who's generally disagreable. I enjoy a rather passive personality, because I am so, it's condusive to calm, to reflection, to conversation, to understanding. Lots of people might be cute on the outside, but horrible on the inside. While I'm sad to say I wouldn't have the, I don't know what the word is here, the "honor" to date someone who I don't find attractive solely based on their personality, but it wouldn't take me much as I'm not a guy that goes necessarily for looks and I find that, in 99% of cases, all women have something special about them that gives them their own shine.
Sadly, it's why I'm still single. Have trouble meeting someone I wouldn't want to shove in the nearest ditch after being around them 30 minutes LOL!
