Is this wrong if she don't know I'm gay?

Ok so I'm gay but no one knows but my friends at different schools....so I come to a new school and in my there is this really cute girl and she doesn't know I'm gay and one day when we were taking pictures we were standing on a table and I was holding her around the waste but I was talking to her about gay people and she was all like ewe and gross and stuff like that so I never told her so I can still huge her around the waste and all that kinda stuff we also hold hands skip down the hall ways just like weird friends....but I don't want to tell her so I can keep doing all these things but is it wrong not to tell her?...I dont think so...but then again I am very lost right now!! •_•
