GIRLS: DO YOU OR DID YOU EVER TEST YOUR BOYFRIEND'S INTENTIONS BY HOLDING BACK ON SOME PHYSICAL STUFF?

I want to know if my girlfriend is holding back on tongue kissing to find out if it bothers me. We used to tongue kiss at least once or twice a day and lately we've only kissed with tongue twice, IN THREE DAYS!! Im thinking that she is just testing me to see if it matters that much to me. Should i act like it's not a big deal so she'll just stop testing me or do i tell her how much IT'S KILLING ME ON THE INSIDE THAT WE HAVEN'T FRENCHED AS MUCH AS WE USED TO. Plz hlp
