And, of course, Fix (http://crys.mrks.org/sga/fic/fix-john.html) by the same author. I think the first-time bad!sex for that story even beats Do Over. ^_^ I have almost equal love for both stores, but Do Over wins for humor while Fix wins at life. (If you read Fix, don't miss the alt-pov versions, though I love John's the best. I spent at least a week wishing for Rodney's POV before realizing she'd already written it, DUH.)
There's also crownglass39's Bad Sex series; it's more humor and hotness than all bad!sex, but there's still plenty of it around (plus both John and Rodney are new to different parts of the sex they have in different parts of the series - it sounds confusing but works out when you read, trust me). ;-) Part 4, Drip (http://crownglass39.livejournal.com/80799.html), has the links to the previous 3 parts, part 5 is pH (http://crownglass39.livejournal.com/83156.html) and part 6 is Stuck (http://crownglass39.livejournal.com/84063.html).
Also, Yes, Really (http://community.livejournal.com/mcsmooch/91514.html) by thegrrrl2002? Is my latest favest McShep NC-17 first time gay sex aftermath *ever*.
