I liked the sex in "Obsession-For Doctors". I'd love to read "Side Effects" now and tell you what I think, but unfortunately, I still have to memorize the sectional view thingie *ack*.

With House and Wilson, I like the first timers, which is new. Usually I'm all for established relationships. And in general, I hate first timers in which the two people in question confess their love for each other and have steaming hot sex in less than 2000 words. So maybe it's a combination of these two things that is the reason for me not liking H/W sex.
