Frustrated with sex life girlfriend?

Sup so me and my girlfriend use to have sex like 3 times a week or more. For the past two months we barely have sex one time a week and I have to keep asking her. It's really bugging me because I use to like sneak it in when she was sleeping and she liked it. Now everytime I try todo it she pushes my hands or my dick away. She's alway claiming she's tried but she's doesn't do anything. She use to ask me to eat her out a couple times a week. And now I love doing it so I tell her let me eat you out and let me hog tie you and everything she doesn't want it. She took birth control and doing that three month period we **** a lot then she was having issue with the pill so she stopped. She said she felt like her sex drive left when she was on the pill and it came back a couple days of not taking it now she has like no sex drive. I talk to her and tell her why doesn't she want todo it like we use to and she saying I ask her to much. But I only ask when she doesn't give in to any of my advancement so I'm ok well I'll just ask you before I try to make w move on you. she won't even please me like suck me off or jack me off. All she wants todo is cuddle which isn't a problem but when you're cuddling naked everyday some urges are going to pop up. I don't even mind pleasing myself if she isn't in the mood, but jacking off gets old and I want to enjoy my girlfriend. I can't even watch porn if it's not her because I'm only attracted to her so it's like wtf. We been together 2 1/2 years.
