Hi, need some advice!

After my girlfriend said at the start that she was a very sexual person, it very quickly changed and is now at a point where he has point blank said that sex doesn't bother her and she would happily go without. Obviously you can imagine how this makes me feel. To make it worse I have been the one in previous relationships to go off the book when it comes to sex, but with this one it's different, I literally could make love to her every day. I tell her how much I love her, how sexy I find her etc but it just doesn't work.

When we do do it I am always the one to initiate, and even then I can tell she's not into it as he barely even gets wet. And she just lays there and blatently tells me to cum quickly.

What I find hard is that she use to have all sorts of sex toys with her ex, and she still has some of them. I get the impression it was him that wanted them not her. I've asked to use them in our sex life etc but she's just not interested. She even said to me at the weekend that she doesn't mind if I satisfy myself in the shower or something if it helps me take the pressure off. I've tried to tell her how much it affects me but she just doesn't get it! Why is this and what can I do??!

I have even said to her that is she doesn't feel like full sex maybe we could just please each other with foreplay, but she just said that feels juvenile and if she doesn't feel like sex, she defo won't feel like foreplay. It's very hard to talk to her about it because she just closes off and gets wound up
