Masturbation Issues! Help?

Okay so basically i love masturbation and even though i'm a girl i get so much pleasure from it :) i enjoy letting my jeans and undies down and just exploring :) but anyway recently my orgasms have been getting more noticeable.... when i get a small one i keep playing and playing until i cant keep still and cant stop playing even when it gets uncomfortable i keep going... i've been caught before so parents know i do it. The other day me and my boyfriend met up and went to a coffee shop... when we started talking i started feeling sexed up and then next thing you know im having a lil orgasm in public! then we got to the bus stop and when our privates touched i started doing a sexual moan! am i too addicted to sex, masturbation and love or is this normal?
