One of my buddies got drunk and made a move on a girl, nothing got out of it, but apparently he was overly persistent, and she accused him of sexual harassment with their college authorities. After that my friend has fears of making any move on a girl, to simply avoid legal issues.
What do you do to prevent this from happening?
Here is my take on this matter:
Cut down on drinking goes without saying, but my friend has fears of making a move even if he is not drunk.
Sexual harassment thing interferes a lot with the perseverance of a real alpha male. There's a gray area of her testing you and harassment. You can only learn to distinguish it with practice. But what do you do to practice? - you may ask.
You make a move, you escalate, you persevere AND you always leave a way for a girl to simply walk away. If she can easily walk away and she doesn't, even if she verbally refuses, she is probably testing you. For example, if you decide to kiss her, keep your arms behind your back and just lean in. She can walk away, but if she stays she likes you.
It is a very sensitive topic, especially in the US. With practice you will easily see and feel if a girl is into you and when to escalate, when she wants you. Before you get there, cover your ass, and always leave her a way to walk away easily.
Remember, to always use your judgement, for that you must stay with clear mind.
