Huge generalization right there. I can't say you're entirely incorrect, but I honestly don't think much has changed. I usually tend to watch animes made in the past five या so years, but from what older animes I've seen, they were making boob and boy's प्यार jokes from the beginning.
I swear tons of girls think the way आप do and they should stop. WHO the heck cares if an ऐनीमे girl has big boobs या याओइ in the anime? If आप don't like either one then watch a different genre. However don't complain about it. NO ऐनीमे hasn't completely turned into that AT all.
