Lose Libido Over Time

I’ve realised recently that my libido (and erectile dysfunction) issues become unmanageable after 6-9 months in a new relationship.

I still love the person, more than ever, but there is a loss of sexual excitement that helps me to overcome anxiety and focus issues that I have less of early on.

This then begins to be a problem for them and often leads to the end of the relationship.

Does anyone else have this happen? Any suggestions?
