Orgasming from Cunnilingus

Madison

My boyfriend is such a gentleman, and he eats me out regularly. However, no matter what he does, he cannot make me cum from oral. Since I am a virgin, the only way that I can cum because of him is when he sucks on my nipples and I rub my clit. I want to cum because his tongue. He tries so hard, and I feel like there is something wrong with me. Any tips?
