I think you are downplaying CorbinFisher's careful scripting of their guys back in the day and those "don't kiss me" shots were very much done on purpose. Which is not to say he was into kissing guys, but rather, he balked slightly and they said "great idea" and ran with it.
They did an excellent job of creating a tight narrative for all their guys and it made many of the pairings seem a lot less random and much hotter when all the guys were playing a specific "character"
Also I don't like anyone touching my dick after I cum - it's sensitive AF and given that it may have taken a while for Gabe to get and stay hard and fuck and cum, his dick may have been extremely sensitive by then. Or he was freaked out by a guy touching him. Or both.
