Do you think the British royal family would / should allow members to marry people who are infertile?

*DISCLAIMER* these are not my personal views and is not meant to offend anyone. This is simply a conversation about how you think the royal family would or should handle such matters.

Obviously the main goal within the royal family is to keep their bloodline going. Clearly that indicates that they would never allow any gay marriages to occur within the family.

However do you think they would allow a member to marry someone who suffers from infertility?

Do you think they should be able to marry whoever they like no matter the potential outcome for the monarchy?
