Lost: my orgasms!

I've been with my boyfriend for nearly 11 months now and at first it was great, but after a month I started having trouble orgasming. Now I barely feel anything and I feel like it's impossible or that it'll never happen. I still have sex with him cause it's fun, even if I don't feel much. We've tried everything, including counselling and toys. Any ideas why it's happening or how I can fix it?
