PROBLEMS ORGASMING WITH PARTNER

Lauren
How can I "train" myself to get use to orgasming by my partner? I use dildos and other sex toys when I masturbate, and I usually only actually orgasm if I'm in the bath using the faucet against me. I don't know if this has anything to do with it, but my boyfriend pointed out that my clit is hard to find. I never really thought about this before but I defiantly have a hooded clit. 
I want to be able to cum from him. I always get close or it feels good but never climax. I'm going down to his house this weekend to visit him.. what should we try so that I can cum for him?
