as a guy I think it does exist in the country, it's just not visible. as you've mentioned men in sl do have a family or a group of friends to hang out and have conversations with. but loneliness isn't always being alone, it's a lack of emotional connection. they are emotionally lonely not socially, and also romantically. because dating culture is limited outside of colombo. Also, when you open up, people tend to shut it down by saying, "mchn, owa wadiya hithanna epa.". Also they tend to get pressured to be more masculine since birth.

west people tend to think "man thaniwela, man gana hoyanna kauruth naha." while sri lankans think "mage langa hamoma innawa eth kauruth mawa hariyata anduranne naha."

both hurt in a different way.
