This has been a problem since the internet and personal computers began.
About twenty years ago I read an article about the huge numbers of young men who had given up the work, bother and fear of rejection that goes with real life relationships and instead just contented themselves with "steady relationships" with their favorite internet porn stars.
Some had started visiting those sites at about age 14 and by the time they had their first, real life date they had expectations that could not be met by real girls and were disappointed and returned to their imaginary friends.
