"Can you recommend a good lube?"
Most people have heard about KY Jelly. Did you know that there are many options?
Tool shed, a sex toy store in Wisconsin has a website and lube 101 is one section. Great place to start.
Good vibrations has spreadsheets that offer a comprehensive lube chart organized by the main ingredient.

Talk about what you want in a lubricant, how much lubricant you think you need and afterwards, or during, whether it is enough. When surveyed, many women say their partner underestimated the amount of lubricant needed and they did not feel comfortable asking for more. As the lubricant was applied, was it warmed up with the hands or put on cold? Did you talk about it? Did you add more lubricant as you noticed that more was needed? Did you ask each other for more?
"Hey, I think it is time to add more lube. I really like it when you warm it up in your hands." was one very direct suggestion.
