Yes, several, including people in their 60s and early 70s (that reflects my social and family circle, by the way, nothing else). And countless people who've discovered that romantic relationships aren't all they're cracked up to be if it's not the right person for you. I didn't have a boyfriend until I was in my very late 20s, and even then it was more of a fling. (I was way more committed than he was.) Then there were often gaps between subsequent relationships, often due to travel, work, family responsibilities, illness...I could go on. And I did lots of what were regarded as the right things - joined clubs, went to evenign classes, took up hobbies, did speed dating...I never tried online dating but I do have a few friends and family members who did, and it worked for them, though one friend pointed out that you really do have to kiss (or talk to, anyway) an AWFUL lot of frogs, as it were ;)
It doesn't mean I haven't had an interesting and fulfilling life, though. (And I think there's some left to come!) I do now live with someone, but it's platonic, pragmatic, and not in any way a romantic relationship.
I was given some very good advice years ago which was that if anyone judges you for not being in a relationship or being inexperienced, it says far more about them than it does about you.
