Our society has taught men that they are creeps. If they stare they are creeps, if they approach you might run in fear, they are constantly shamed for being sexually interested in females.
You have to give them an "It's ok" symbol, like a smile when you see them looking.
If they don't get a neon welcome sign, they are likely to feel like they are "Being creepy" or have somehow just made you uncomfortable.1
