What should I do in a situation like this?

Hi,

So I am dating a girl and I've never done that before (I am 17). Everything is new. We text almost every day, and she is iniating convo's too. We went yesterday on a second date, it was super fun and she liked it too she told me. After the date she sent me a text that she had a great time. BUT, whe havn't kissed yet and I haven't broken the touch barrier either (what is good way to break it). As I said this is all new for me, so maybe this is normal. I really don't know what to do.. I just could not find the perfect moment.

She invited me to her birthday "party" next week, and I said yes. She invited a couple of people (but not alot).

Is this potential relationship saveable and should I go to the party? Or should I accept a "friendship"? And if this is saveable, what is a good 3rd date idea?

Thanks in advance!
