Congratulations!
Different people can have remarkably different thermal needs, especially on longer cave dives. I just finished a week of cave diving with Natalie Gibb in the Youcatan. I just wore a 5mm suit and no hood, and I was toasty warm, even on dives approaching 2 hours long. Natalie was heavily dressed in layers of neoprene, and she said she has never been warm in a cave.
I got Ginnie Fingers when I was training. I had some of that first aid stuff that you can spread on the would with a brush, forming something like a new layer of skin. It helped. After that I learned to do it more with the palms of my hands and without using the fingers.
