Spam comment : In my 20s I made the  error of marrying my childhood sweetheart, the first  lady I  ever before  copulated. We have  3 teenagers  currently and the  marital relationship is still  solid. Five years  earlier, we decided to move out of London and  got a big house in the countryside. It is beautiful,  yet the commute to  job is  way too much to do  on a daily basis.  Therefore, I started  remaining in London three times a week.
