Orgasms

So I've been with my boyfriend about 6 months now and I don't think I have orgasmed...he orgasms every time and dont get me wrong the sex is fantastic and I most definatley reach climaxes almost every time and it's amazing but with my ex (I'm only 18 so this is the second person I've been with) I remember orgasming and squirting and everything. I get really wet and I think he mistakes that for me orgasming and I don't particularly mind because it is still amazing sex but has anyone got any tips on how to increase arousal or make sure he hits the right spot to orgasm without being too obvious to hurt his feelings?
