To detect a one see whether he going to finger your ass first. To detect a zero see whether he ask for you to finger him or he going to lie there and scream like a girl? ??
I guess top not really enjoy being finger his ass
But i know some of my friends do like insert their finger cause they like to interact even they are 0
Top don’t want anything in his ass
I'm 1 but I like being fingered
I could only accept being drilled by fingers
I am 1
Being screwed by a muscle 1 is definitely exciting!
