Slingshot: I have an agreement with myself to not date anyone from work, unless I really, really have to (you can never anticipate all scenarios, after all) because, as pointed out earlier, gossip runs through a workplace very quickly. Plus a messy break-up can be awkward when you still have to work with the other person.
It's easy enough for me to do this, because I have a lot of outside interest, but I recognize that other people's jobs may take up pretty much all of their time, ie the available pool of partners is basically workmates. So do it, but try to be discreet.
What I really wanted to talk about was the idea of worrying that a woman who's interested in you is only interested because she knows you've got a big dick. When I was a teenager to early twenties, I used to harbor suspicions that any girl who was hell-bent on getting intimate with me was doing so because of my well-known size rather than because she liked me for me (which, as with many things, was true for some women all of the time, partially true for some women some of the time, and not at all true for others). It led to me having one-night stands with women who were interested in size, but going out with women who were indifferent to it.
It was later that I came to understand that just because a woman is interested in the size of your dick, doesn't mean that she's not more interested in you as a person. Not that anyone has ever said to me, "I love the fact that you're well hung, but I'd love you even if you had a small dick," mainly cos it would be such a peculiar thing to say, but that would apply to my best adult relationships.
The upshot of what I'm saying, and I know it's nothing astounding, is: Don't discount someone just because they appreciate the size of your package. There's more to you, and there's probably more to them.
