Girlfriend doesn't want sex, which makes me unsatisfied

i perfectly understand that my girlfriend doesn't want to have sex yet but whenever we do foreplay i always feel UNsatisfied. I put in my best effort to make her org*sm and yes, she does make me org*sm too using her br**sts.. but it's kind of getting old, i would really like to have her s*ck me off but she doesn't approve of oral sex and it's really getting me sexually frustrated and yes, i still respect her decision of not having sex but what really gets me is she doesn't find OTHER ways to satisfy me..

any views on this?? :$ :$ :$ can anyone suggest a new type of foreplay to do?
