She's got large nipples, and I thought this was basically the greatest thing ever since the dawn of time, but I was just sort of like George-Takei-voice "Oh myyyyyyy" and she had always been self-conscious about them, because apparently women erroneously think small nipples are attractive to men or something?, and so she thought I was saying something negative.
I was not.
They were amazing. They are amazing. Your boyfriend almost certainly thinks yours are amazing too.
If it turns out I'm wrong and he was being a dick, then call him out on that obviously and stick up for yourself.
But there is a 99.99% chance he was extremely pleased with them. Sometimes, being extremely pleased with boobs turns us into quasi-verbal creatures slightly dumber than a dog. Apologies for any confusion.
