Being christmas break my LTR has spent several nights at my place and so I wake up horny and ready to fuck. The last two mornings she strait up refused sex. The first time it happened I pulled away and showered and ate breakfast. She came over and rubbed my back and chest until we were in bed fucking. She refused again this morning and so I pulled away again. This time she tried to tell me that morning sex is different for girls than guys, but I wasn't having it so I just told her to shut it and fucked off.

TLDR: girl refuses sex two mornings in a row

Is this normal or should I take some action on it
