i have been dating a girl for almost 10 months, we used to masturbate eachother and take showers together quite often(no sex). But she hasnt made me cum in the past 4 months and has really only tried once in those 4 mothns. Usually we just do her b/c i take to long and everytime we are about to, her parents come home or something. In the past 2 motnhs she has been in a huge slump and she wont even let me touch her. She finds it funny to make me horny and not do anything about it, i dont get how she can turn me on so fast and i cant even turn her on, well atleast thats what i think on the count of she hasnt been horny in the past months. I really just want to know if this is strange or not and also if theres a way i can get her out of this slump.
And another thing, her parents were gone the entire weekend and we didnt do a single thing. Also she said she was going to be sleeping home alone and knowbody would be home until the after noon of the following night, and i said "omg can i sleep over" and she just laughed in my face and screamed no. then i asked why and she said it was b/c im a guy and all we think about is sex.......i was compltly offended. does anybody think that its weird that she wouldnt let me or iam i an fool and of course i she shouldnt let me sleep over?

PLEASE HELP ME!!! ANYTHING WILL HELP!!!
