Everything was already written, voice-acted, and animated. The fact that Ichigo made pointlessly-specific statements about pistil-to-pistil not working cause of "boy and girls!", then mentioning how painful that sort of relationship implies one of the following:
1. She's a lesbian because her male crush rejected her.
2. She discovers girls are "way more fun" after Ikuno assaults her, disproving that she went gay earlier. This still doesn't help her case because the back-to-back comments about heteronormativity was a setup toward "Wow! I was wrong the whole time! Girls CAN love girls! Pfft, boys? Who needs them!"
Regardless, she still needs a Stamen to pilot a Franxx, so while Goro is stuck with her, there's a big chance their synergy falls apart due to Goro's self-worth plummeting to the other side of the Earth. Getting cucked by another guy is one thing, but losing out because your crush would rather be a lesbian is both a cop-out and the biggest *FUCK YOU* possible.
Being Goro is truly suffering...
