Alright, the tailbone thing didn't really work. I started caressing her there during her daily evening bath. I prefer to bath her out in the garden. I´m not going to have her slipping on the tub or running off all drippy and stuff on the house.
She seems to enjoy it, even if she gets even redder at the time, anyway.
So I had her on hands and knees and was washing her hair (she has platinum blond hair, tho I have seen most drow seem to have white, is that important?), she was behaving quite well, when I started rubbing at the base of her tailbone.
She got really, i mean REALLY tense, and shivered a lot while looking at me, making a lot of noise (I swear you could swear they can talk, sometimes. What I wouldn't give for someone to decipher animal speech), but eventually settled down and seemed to relax, then tense up again, and made this cute little meow/cooing sound and relaxed again.
Afterward I noticed she bit her lower lip somewhat fierce. Is this normal behavior? Anyway, she seems a lot calmer now, and I don´t have to drag her to her milk bowl anymore. She keeps climbing on my lap when I´m watching tv, tho, and soon as I try to pet her, she jumps right back down and runs out of the room, then stares at my from the threshold.
