I think so, too fast for him. I mean, Minato skipped the neck because that was too sexy I think so going in for a blowie was probably too much to compute.
well, they did mention that him splattering was all sexual desire but he didn't feel like he was about to splatter when they kissed bc he truly felt wanted and loved and it felt like there was more romantic love than just physical attraction.
he did almost splatter at first but after slowing down a bit, he got some time to prepare himself enough emotionally to accept it but ig they were interrupted before he got to splatter???
idk, these are just theories but I think I'm pretty close
Because he scared??
