Yes, some girls are definitely attracted to hair on guys. However, when i was dating my ex I shaved my legs once or twice and she REALLY liked the smooth skin. Too bad she HATED even the thought of crossdressing.
But I also agree with what some others have said, once you start you'll never want to stop. Right now I only have my thighs shaved. Another few weeks and i will be shaving my whole legs since they will be under jeans at work.
