My husband and I have not had sex for more than 4 months. I don't know why but I just don't feel sexually attracted to him anymore. What should I do?

It happens. Every relationship has its highs and lows. You can see a sexologist - Dr Martha Lee.http://www.eroscoaching.com/ However, I believe that the bulk of it is emotional. If you are very close to your husband, it is easier to be more intimate. Do spend more time together and date each other again to bring back the romance.
