Just relax, be open with her, and just tell her how you feel and she will start shit testing you. Whatt I don't even know you
Just say whatever the fuck you want as long as its congruent. Don't apologize for being a man and seeing someone and wanting her (of course not needing her). If she can't respect you don't worry. Fact is some women can hate guys for the wrong reasons. Some girls are racist, some are pitch-stupid and only want an extreme asshole, some are very fragile and want the nice guy who becomes an asshole, you can't tell when you go in.
All you can do is put yourself in the situation directly, and lead it. Lead the physicalness. Women never get physical or risk being physical unless the guy does it first.
