Hi, I am a guy. While going thru some of the postings, I found women complaining about their husband's lost sex interest. I would suggest two things, which I have experienced.
1. Make your husband to workout on everyday basis, which increases the sex power.
2. Use sexy attire whenever you need sex to arouse your husband.
3. Some yoga actions do enhances sex desires, which would help to both of you to increase the sex power. I found those actions really awesome.
The action is called as 'halasan'. You can get more information about this action if you search on google.Com
try it and see the difference.
