This kind of shit comes up on /trv/ all the time. It usually becomes a screaming match of trolls pissing in an ocean of piss.
I’m not actually single, but I lived until recently in the middle of Europe, where I used to take short international trips by myself (long weekends, 2-5 days) at least a few times per year. And when I was last living in the US, I took one longer solo trip (a little over three weeks), but met up with my wife at the end of it for two weeks of travel together.
Solo travel can be really enjoyable if you like your own company and enjoy seeing new places. I’m an introvert; I socialize well and sometimes enjoy it, but also find it taxing. I find spending a few days alone, fully in charge of everything I see or do, without any need to accommodate anybody else’s interests, refreshing and fun.
I also used to travel for business, and would stick a few vacation days onto my business trips for some solo sightseeing as often as I could get away with. I would spend most of those trips in back-to-back meetings, talking with people all day, so just being alone for a day or two at the end, not talking to anyone, was a relief. I suspect that some of the single men you and others have seen around the world are probably doing the same thing.
