My bf loves to do it but I don't like receiving. I just tell him no. He gives me the pouty face and sometimes I'll let him but it just doesn't do anything for me. Makes me raw and then I can't enjoy sex afterwards. I have bled before from just going too long. Luckily he is very conscientious of how I'm feeling during and stops if he notices I'm just not into it. I hope your husband listens because it just makes it not fun after a while! But also, try and take it as a compliment. He is soooo into you! But yes, I would definitely tell him your feelings on it.
