My boyfriend is a total munch and I’m very grateful. However, I am not getting anything out of it. I try to give him direction and tell him where my clit is but it doesn’t seem to help. He can’t find the clit and keep a good rhythm. His tongue is kind of limp so it just feels like he’s slurping. I appreciate the gesture. I want to tell him but I don’t want to hurt his feelings. What should I do? How else can I give him constructive feedback?
