Hi I'm a 15 year old guy and have a question about kissing a girl. Ok so I've known this girl for about two years now and I really like her. she was my first friend when I moved to a new school. We hung out a lot and I quickly figured out she is a lesbian. But on Facebook she wrote a post that said something like " I don't care if your a girl or a guy I'll date you as long as I like you and you make me laugh" so that got me confused. I do make her laugh a lot though. And she always has a smile on her face when we're talking or walking to class together. And a few months ago she started saying she loves me while we're hugging when we see each other in the morning, and after school. But I recently figured out she is moving to Texas next week. I was wondering if on the last day we see each other at the end of the day, should I kiss her? And if I should, where should I?
