It's rare to see copious amounts of natural lubrication in older women, mostly just enough for a few minutes sex before needing a little help from a tube or bottle. Men have viagra and other treatments to overcome the wear and tear of aging, woman only really have estrogen treatments which don't agree with many women's health issues.

Just like with the more orthodox version of national service the men would benefit from interpersonal skills learning and go on to properly service women of their own age, with maturity and respect.
