Help?

So my girlfriend and I have been dating for 4 months now and had crushes on each other for over a year. All of our friends and family support us, and we’re still going strong. Lately, people keep mentioning how weird it is that we haven’t kissed yet, even her own parents! She even mentioned it to me, but neither of us really knew what we wanted to do.

I love my girlfriend so much and I don’t want to do anything to ruin our relationship. Am I waiting too long to make a move, or would it ruin our relationship if I did anything? Please help!
