As much as "we" (all of us on this board) want to have a fulfilling sex life, it is not a necessity of life - it is a desire, a very pleasureable desire but not a necessity. I don't know how you can label not having sex as being "unhealthy"
For the same reason I would label not getting exercise or sunshine as being unhealthy. Sure, you can sit on your sofa all day and take Vitamin D capsules and it won't kill you, at least not right away, but it's still not healthy. I would seriously estimate that I have added 5 years to my life by leaving my SSM.
