When he goes down on me I want to cry..

Hey. So whenever my boyfriend goes down on me he gets really intense on my clit with his tongue. And the feeling it gives me. I can’t describe it. It’s so powerful and intense in that moment I want to cry. I almost want him to stop. It feels good dont get me wrong but. It’s so much it’s like my body can’t handle it. Does that happen to anyone else? I feel so odd when it’s happening and I can’t even moan. All I want to do is like whine almost. It’s strange AF.
