I've only watched a handful of episodes of Star Trek, and it was a deeply strange experience. Wasn't there an episode where Spock went into heat? (I also had a sci-fi show I watched as a very young child and still remembered details from long afterwards, actually, although in my case it was Red Dwarf.)

is one reason why I enjoy both reading and writing a variety of intense hurt/comforty tropes, ranging from characters going through some kind of hell together (torture, survival in the wilderness) to things like sex/cuddle pollen, involuntary soulbonding, and sudden onset telepathy. Some people just need to be jammed into each other's proximity and then forcibly held there.

All excellent stuff! I've actually attempted this in my fic - they're trapped and isolated in an inescapable wasteland together, unsure of how or if they're going to survive - but, inconsiderately, they still won't make out.
