Have I just learnt to orgasm?

I'm 17, and have been masturbating since I was about 12. I've always had what I described as mini orgasms. They felt good, but were never enough to make me moan loudly. I've been with my boyfriend for a year now, and he always gave me the mini orgasms. For the past week or so he's been giving me amazing ones though. It lasts for a half hour, I moan uncontrollably, and the pleasure of it is just amazing!! It's never been as amazing before. Have I just started having proper orgasms?
