A little true advice

CC
I have been married for 35 years. We are no longer spring chickens and things became a little more work over the years. I have had to explore so other avenues in order for my husband to attain and maintain full erection. I did a little research and was told a development car called a we vibe could add some spice to our relationship. I purchased one, but do not know how to tell me husband about it or suggest we use it. I do not want him to think I have gone all perverted. This device was not cheap and I do not want to waste my money. Anyone have any helpful suggestions or knowledge of this device. Does it work? How should I introduce this into our sex life, or should I just leave it alone?  We are not young, but I am not ready to just give up.
