No need to worry about this problem .
There are so many lubricant products available which you can try .
First of all try vitamin E oil.Vitamin E oil is considered one of the best natural ways to boost lubrication and eliminate dryness in the vagina. It's used as a suppository placed directly in the vagina and can help restore proper function in the vagina, as well as restore thin vaginal tissue. Vitamin E suppositories can be bought at many places where feminine products are sold.
KY jelly can also help in this regard.
Moreover,one hormonal cream Premarin(it contains estrogen) is quiet helpful for increasing sensitivity and lubrication.
Drink plenty of water and relax.
Love itself is a strong stimulant at any age.So fall in love if you got a chance and forget rest . :) Wish you good luck.
