You never forget your first time. Or your favorite TV characters first times, if you're like us.
In honor of tonight's Big Bang Theory's big bang (sorry, we couldn't help ourselves) between Sheldon (Jim Parsons) and Amy (Mayim Bialik), we thought the time was right to look back at all the other first timers who came before them.
Whether it was Ross and Rachel's under-the-electric-stars sweetness from Friends, Connor and Oliver's deliciously dirty seduction on How to Get Away With Murder, or Downton Abbey's sex so good it killed a man, we've gathered all of TV's recent most memorable first times for a little romp down memory lane.
Check out the gallery of firsts to reminisce about all the frisky fun. Just don't blame us if you need a cold shower after.
And while it didn't quite crack our list, check out Gabourey Sidibe talk about her big sex scene from the second season of Empire below.
