It might be a need if you're weak minded and let your urges control you but I know plenty of men who are so self absorbed with their success/job, sex might happen once a month for them. They obviously focus on something else they think is more important...or they jack off to simply get a release.
If there is any
thing on earth that controls you to the point of being "sick in the head" especially something like meaningless sex, that speaks for itself. It's not sex you need..it's therapy!
I have several Aunts who are widowed and have made the choice to never be with another man...they are doing quite well living ife without that one thing.
I can see the longing for companionship and affection, but I am looking at the mere
definition of what a need is...can't really argue with facts. According to that...sex is not a need.
I know many people who make the decision to never have sex until they are married, and some live a life of celibacy...have yet to attend a funeral in any of those cases. I think too many people try to convince themselves they need something just so they can do it and feel justified.
