I disagree. "Others" are not involved in sex. Sex is not a life or death issue, and it's not a whole part of my identity. As I get older and sex becomes less - becomes it does as you age - it doesn't make me any less of a person. So, say, for instance my husband became impotent (he's not, just saying), I wouldn't bug him to take Viagra or any of the other drugs, because that would not be good for his heart and could risk him leaving this earth a lot sooner than otherwise. So if there came that point, where sex was no longer taking place, would our identities be changed? Would we no longer be husband and wife? Would I be a different woman and he a different man? I don't believe that to be true, because our identities as husband and wife are based in a lot more than sex. Hence, that is why I would bring him a bowl of soup if he was sick.
