This question is inspired by the one in "Meet and Greet" from the lady who says that her boyfriend gets erections from sneezing. Whenever I have a fever, my flaccid penis (normally very floppy) seems to tighten up, getting smaller (in both length and width) and becoming less flexible. It does not become hard, just a bit stiffer. That's hard to explain, because it's not from an influx of blood (as in an erection). That would make it larger, not smaller. I can always tell when I have a fever from this "symptom." Does fever have this effect on anyone else?
