Also complaining about getting hit on? Really? A person finds you attractive and wants to talk to you. What a monster.
"But I hate that my physical appearance and gender connotes so many (invalid and ridiculous) assumptions."
What is ridiculous about an assumption that is 95% correct in today's world? Perhaps it will be a ridiculous assumption in 5 years, and definitely 10, but it's not far-fetched to run into guys at these events who don't interact with women ever in their day-to-day work lives.
