Lubricants are wonderful at any stage of life to support the natural lubrication of the vulvar and vaginal tissue. Like anything, they all have their pros and cons, so choosing what works best for your body to achieve your goals is always what you are looking for. I have summarized for you what each type is, when and where it can or cannot be used, and my favorite brands right now that are safe and clean. Always check with your provider if you have a specific condition, allergy, etc...that might require something unique.
And remember that lubrication during intimacy does not have a direct relationship with arousal. This is the top reason women tell me that they are embarrassed or ashamed to use it, so it is important to know that many other factors contribute to lubrication.
