Ah, I wondered if there was a poll on condom use between humans. I'm intrigued by women that rarely or never use condoms with new men, even in one-night-stands. From surveys I've seen, both professional and just on forums, the condom use numbers here by F (females) seems to match up. About 1 in 3 are more strict on condom use. The other two-thirds are some variation of "sometimes", "rarely", or "never".
I answered other, because more than 50% of the time I'll go bare with a new woman, but.... it depends on various things like type of birth control, her knowledge of sti's, etc....
