Climax or Orgasm?

So basically I'm not sure if I've had just a climax or an orgasm. 
When I masturbate I do come to a climax and it feels really good but it's not like explosive like people say. As soon as that good feeling is over I don't want to continue at all and just feel like I'm not horny anymore. 
I haven't tried any toys and I'm still a virgin but I masturbate almost every night. Please help I JUST WANT SOME GODDAMN ORGASMS
