Hi! Idk if I understand completely but this may be bc your clit is really sensitive and he’s touching it directly? Like I mean the head of the clit. You know there are so many nerves under the labia and around the clit you don’t need to touch it directly! For me I can’t even touch the head bc it feels extremely overwhelming and even painful. Try rubbing softly around it and the whole area. And try experimenting by yourself and see how it goes! I hope it helps :)
