Kissing problems

I have been dating a girl for almost 2 months and I believe she wants to kiss but I'm not positive. We have never kissed before and I feel like she's showing signs. For example, last night was our homecoming dance, after it was finished the group we were in went back to her house for an after party. When the party came to an end and I was about to leave, we both went somewhere that no one else was at, and we talked for a minute. After that minute, we hugged for a fairly long time and we talked about how amazing the night was and then we stopped talking and just stood there hugging. At that moment, the thought of kissing her came through my mind, but... I immediately thought the worst. One thought was, "What happens if I kiss her and she doesn't want to kiss? Then It's weird and awkward" and the other thought, "What happens if she does want to kiss and I don't kiss her because of the first thought". This was my worst problem... I have no clue what to do and It'd be great if someone could give me any advice. I really don't want to kiss her and have it be weird because she doesn't want to kiss and I don't want to not kiss her and have her be sad/bored because she want's to kiss. Also. Yes, I'm in high school and I'd really appreciate if you could just not waste time by saying "Don't be in a relationship. You're to young" Please actually try to give some tips that are useful. Thank you to anyone who takes the time to read this. I really appreciate it.

Go in for the kiss. Have zero fear. Most likely she will kiss you back and who knows you might even go further. I highly highly doubt she will reject a kiss given that you have dated now for 2 months and have had some intimate moments (alone hugging etc). I wrote a post looking for help on something completely different but it loosely relates to your issue. I dated a buncha of girls here and there and due to the type of fear you're having, didn't kiss them or kissed them but didn't push for sex. And in all of those instances, i would have gotten what i wanted i had the courage to go for it. Just go for it, seriously. Even if she doesn't kiss back, she will appreciate the courage and kiss you later. There is NO way she'll break up with you because you wanted to kiss her. Have fun and be confident.
