My headcanon is that after he accidentally got knocked up, he just sorta figured there was nothing he could do to avoid accidentally having sex, so what’s the harm in doing it intentionally? At least that way it’s easier to recognise all aspects as consensual.
Sorry but I can’t say I’ve heard of any fix for this. I’ve checked on nexus but can’t find anything (granted I could be missing something).
Impressed you got your HOTAS working though. Agree it’s a complete nightmare for no good reason.
