The X in Toyota Mark X denotes '10', the Japanese in their infinite wisdom rolled out the Mark Ten = Mark X was born.
As far as the 'X fragrance card' and the correlation of the X to the word 'SEX' is concerned, you and i are products of the act. Embrace it. If done right within the boundaries of taste, you and i were the result.
Have an open mind to outside stimulus. If you have an opinion, voice it but weigh out the variables before you speak. Think twice and speak only once. This way you shall tolerate more and live a fuller and more rewarding existence.
Just my two cents worth.
