Also, not a female, but 100% human.

I have not had luck with rolling clothes. I must be doing it wrong, but when I roll, I get tons of wrinkles, if I fold carefully, I get very few.

Otherwise - I second everything philski posted. The bit about cooling down is essential. If you shower before you leave, cool down completely, towel off and change clothes, the sweat is not an issue. I thought the idea was really gross at first, but I have since realized its really fine.
