>>7027373G1 cartoon Starscream and Megatron is more gay than anything in IDW.
Confirming relationships doesn't compare to the actual feeling of an old bitter couple.
IDW was mainly just shrugging and going "well, they have genders because Primus said so, but since they don't have junk and for like 99% of Cybertronian history there was no girls, anyone can just kind of couple with anyone since its the same thing".
