My flaccid varies a lot too. Sometimes it's a shrimp, sometimes it feels heavier and looks longer. That's normal. Plus I'm stressing easily about little things (no pun intended, heh) too, and that really effects my flaccid size. Just relax, try to get into a good mood. I know it's not always easy, but thinking about it too much is not going to help. The more you stress about it being small and shriveled, the smaller and more shriveled it's going to be.

And as someone suggested, try doing those helicopters after heating up.
