Yes men can live without Sex but how possible is that because men love sex to the core that most of them can't even control their libido.
So, how can one controls his huge?
I'd say it's possible, but I'd advise you to avoid feeling pressure in either direction, don't feel pressured to decide that you absolutely need it, or pressured to decide that you can live without it. Try to be content with figuring it out as you go. Sex is not required in anyone's life - you can live a sex-free existence with no problems.
