Are you conscious when you ask a girl certain questions to figure out if she would be good for a LTR?
Most of the time no, but if you hear certain answers, it leads you to a certain way of thinking about her.
Are you conscious when you decide a girl doesnt fit your beauty threshold to sleep with her? Sometimes but often you just know.
Personally I dont like the term shit-test because it implies its something negative and I feel its something both genders do. Girls usually do it more being 'the selector' and needing to filter out a lot of men though.
Also, I find that if a girl is shit-testing you, it means there is still potential. When girls have made up their mind, they dont shit test, they either ignore you or politely remove themselves
