Of course, as your romance progresses, you’ll eventually want to be able to openly voice your insecurities. Healthy, loving relationships require support through communication, and allow partners to become better versions of themselves — so occasional deeper conversations about insecurities are not only appropriate, they’re necessary now and then. But steady off-handed self-criticisms for the sake of attention will only frustrate your boyfriend in the long run.
Regardless of what your boyfriend thinks, if your negative self-image is affecting your overall mental health, and talking to your parents and most trusted friends isn’t helping, you might want to seek professional help. Hey, I went to a therapist for a couple of years, and it helped me get in touch with some of my own personal issues (though I’m still working on the “chicken-legs” thing).
Just remember that your boyfriend chose to be with you specifically because he thinks you’re hot. You don’t need to convince him of that or talk him out of it! The more you’re able to love yourself, the more your boyfriend will love you for the confident, self-assured girl you are.
