l turned down my boyfriend for a kiss because l didn't brush my teeth😀!
Unless your mouth smells really awful without brushing your teeth, go ahead and kiss. Many couples kiss in bed in the morning despite having morning breath, and they don't mind! If it really bothers you, just kiss with your mouth closed - and explain to your boyfriend that you're self-conscious about your breath, to make sure he doesn't feel rejected.
