i've been a pesco vegetarian (fish/eggs/dairy) for about nine years now. It started when i'd get sick after eating meat. Not violently ill, but my stomach would be upset for a while and churn like it was having trouble digesting it. So i decided to cut back, to add more turkey to my hamburger (i eventually went all turkey to no avail), and everything except fish and eggs made me sick. So i gradually became a vegetarian from the simple lack of eating meat. i kinda hate the title of "vegetarian" since i don't feel i'm a true vegetarian, but it's much easier than listing off the meats i don't eat to people. In any case, i'm happy not eating meat and i find a lot of foods benefit from not having to fight with the flavors of meat. On the other hand, if i wanted to eat meat tommorrow i'd slowly transition back into doing that. It's a diet, or a system of eating, same as other people. It's not my personal prison.
What really sucks is moving from an area of Michigan with a heavy mid-eastern influence to a small southern city. i was within walking distance of a dozen or so mideastern eateries. Now i'm in a place where everything has pork in it and tons of salt. i'm glad i can cook, or i'd probably starve to death, vegetarian or not.
For the person who scoffed at the idea of pasta without meat: use a robust tomato sauce and/or basil pesto, with small pieces of sun dried tomatoes. You can have very hearty pasta that doesn't need meat at all to taste right.
Bingo. A lot of people make spaghetti with way too much meat anyways and a bland spaghetti sauce. When made with a fresh pesto and a good spaghetti sauce (i use Barilla), the difference between this and your average ground beef and Ragu is night and day. The absence of meat allows the flavors of the vegetables to come to life.
Edit: Is it true that women who don't eat meat smell bad...
downstairs? i went down on a girl who was veg, and i couldn't tell one way or the other since it was my first time, though it wasn't really pleasant. A friend was telling me it was the lack of iron that causes it, but there's several good sources of iron outside of animals.
