I always thought the sterotype was latinas are hot-blooded sexual women. :)
But all sterotypes aside...
In my humble opinion, what goes on between you and your husband that you both consent to is your business and isn't for anyone else to judge. If you want more, the best thing is to have an open communication with your husband about your desires. If he's open to it, you can initiate sexual encounters more often and welcome them from him. Work on doing things to increase your intimacy with him which can be beneficial for lighting a fire to your experience in the bedroom.
Here is an article I wrote about low libido. It is directed at women's health, but could be useful in helping your husband if he's experiencing troubles with intimacy:
