Cold/drowning Steve + two specific fics

[korpikarppi.livejournal.com]

I'm new to LiveJournal and this is my first post, I hope I'm doing this right. :)

I'm looking for two specific fics + some general recs:

1. In the first fic Steve has trouble believing that he's actually woken up in the future and so he's come up with five alternative theories that could explain what he's experiencing (he's hypothermic&hallucinating / he's crazy etc.). At some point - to test one of his theories - he jumps off of a building believing that either Tony or Thor will catch him. There might have been a Steve/Tony pairing, but I'm not sure.

2. In this fic Steve is either bisexual or gay, but is having hard time accepting this. He grew up believing that it was unacceptable and even disgusting. Somehow it comes up that Tony is into men too, and at first Tony thinks Steve is just homophobic but once it comes clear that Steve's actually having more of a coming-to-terms crisis, he's understanding and tries to more or less subtly help Steve to deal by leaving him pamphlets to see and stuff. Steve talked to Bruce at some point and Bruce asked Steve if he had ever considered that there was "nothing to fix", or something along those lines. Steve also called some LGBT help line and gradually learnt to accept himself for who he was. I'd say it was a Stony fic. It might have been a verse other than the movie one.

3. Any fics that involve Steve almost drowning or being really cold and reminded of his time being frozen? Happy endings prefered, and either gen or Tony/Steve, please, if you happen to know any.

Thank you in advance to anyone who takes the time to answer!
