Sexual harassment is one thing, but how do you deal with peers or contacts who see you as a romantic possibility rather than an expert in your field? I had a very hard time networking at a health education conference last fall because many of the men I met only seemed interested in flirtatious conversations, no matter how many times I redirected to professional matters. "Nice/polite" and "flirtatious" are too often conflated, and I found it difficult to discourage flirtation without being rude. How do you make it clear you're only there to network without coming off as impolite or standoffish? Is this a problem that plagues women at every level, or is it a byproduct of being an undergraduate/intern (young, inexperienced, vulnerable)?
