   Summary

   The thing is- and this is something he won't write down or say out loud, not to FRIDAY or Pepper or Rhodey or anyone else- is that Ryland's been back in his life for three months now and they've kissed approximately 47 times (Tony's not counting, but FRIDAY is, even though he's asked her to stop). They've gotten to second and even second and-a-half base- which, awesome, more of that please- but they haven't had sex. Not in twenty something years. Not yet, not fully.

   He's going to fix this. He has a plan.

   AKA, Tony's super-secret-super-awesome plan to have sex with his boyfriend. It doesn't work, and then it does.
