Damon and Elena - The Vampire Diaries
When Damon and Elena finally got together, there was nothing stopping them from acting on their feelings. Elena's brother, Jeremy often walked in on them in the middle of their makeout sessions. That's probably a position he never wanted to see his sister in.
Archie and Veronica - Riverdale
Archie and Veronica seem to forget that other people can see them. Or they just don't care. Even when they're at school they're all over each other.
Tony and Michelle - Skins
We can't forget about the time Jal was awkwardly sitting on the couch trying not to watch Tony and Michelle kissing. The two definitely didn't have any qualms with PDA.
Iris and Barry - The Flash
The Flash established that touch was Iris and Barry's love language and it's adorable. The two are very open about their love for each other and it's incredibly sweet.
Randall and Beth - This Is Us
Although they have gone through their fair share of struggles, Randall and Beth have the purest type of love there is. Anytime that they make a spectacle of it we actually get butterflies.
Nic and Conrad - The Resident
Nic and Conrad were always openly affectionate. Touch is almost like a comfort to them, especially with all the hardship they deal with at the hospital. They're each other's rocks and are almost always seen in each other's arms.
