Boyfriend started sending eggplant emojis

okay so my boyfriend and I have been off and on for 9 years , and we are officially together for 1 year now . and we live together .he never sends emojis. well the past couple of days he has been sending me the eggplant emoji 🍆🍆 yes I am aware this is a sexual thing ...

do you guys think some other girl has been sending him this ? why else would he JUST NOW start sending these to me ?
