My grandmother was troubled by the possibility that I might live with a boyfriend before marriage. She was convinced that I would never get married if I did this.

Over the course of 12 years I had been convinced that HRT did great things, then thought it may possibly even be harmful, then I was simply confused. Now comes an unexpected finding suggesting a positive role for HRT.

You meet that special someone. You talk, you date, oh and did I mention that you two have amazing chemistry in the bedroom!
