Starscream has always been one for physical affection, it's almost as though he can't keep his servos off of you. But, he's never once kissed you.

At first you thought that he simply didn't like kissing, but it had quickly occurred to you that maybe he just didn't know what kissing even is.

Which, to be fair, you didn't either until you and Thundercracker watched a human movie in which the human leads kissed.

"So, you're telling me that the humans... Smash their intakes together and make their glossa fight as a... Show of affection?" He looks understandably sceptical, but humans do tend to do weirder things with their tiny, fleshy glossa. "That sounds gross. Humans have... Liquid in them, don't they? Why would they share their intake lubricant?"

You're not sure either, but every time you've seen kissing, it's always so romantic and perfect.

"Primus, you're such a weird little freak, aren't you?" Starscream asks, raising an optical ridge as you place your servos on his chassis and lean up to get closer to his faceplate. "But, I suppose if it will make you happy..." there's a small pause as he wrinkles his olfactory sensor before awkwardly leaning in and stopping just before his nasal ridge touches yours, pouting his derma expectantly and keeping his crimson optics wide open.

Your own optics remain open as you close the distance, pouting your own derma and lightly pressing yours to his.

The two of you stare directly into each other's optics, both of you thinking how stupid the other looks before the awkwardness takes over and you both seem to push each other away at the same time.

"Romantic! Are you kidding! That was even more awkward than when I accidentally walked in on Megatron watching videos of Optimus Prime!" Starscream turns his helm away, blue Energon rushing to his faceplate as he refuses to look you in the optic for a moment.

When he does though, he immediately bursts out laughing, "You looked so stupid! Your optics bugged out, like Waspinator's!"
