I'm hunting for three fics which are very old so my hopes aren't high but...

The first one is Jensen has gender issues and wants to change sex and become a woman. At first Jared is supportive but then he is confused and leaves for a while. Jensen has surgery and becomes 'Jenny'. Jared comes back and declares his love.

The second is Sera Gamble catches Jared/Jensen having sex against their trailer. She gets the idea for the sex in Heart from that scene.

The third is a really old one - Sam goes with Dean to Jericho but there is sex and Sam comes so hard he has come on his chin! Any help??

Thanks
