Don’t know how to act

I’ve had trouble getting talking or interacting with new people for months now and last night at a club a girl took my hands and tried getting me to dance. I hadn’t drunk, so that probably didn’t help, but I felt so awkward I just stood there to the point she put her hands on my face to shape my mouth into a smile.

Im aware I was supposed to dance and stuff, but I have no interaction with women and I get really self conscious in these situations. I imagine if I was hammered I’d get along fine but its something I need to work on even when sober.

Just not sure how to go about a situation like this should it happen again
