Husband does it by himself every day. Are you sick?

You mean masturbation? This may be due to the following reasons, I hope I can help you:

1, maybe your husband likes watching small movies, where the actors are more beautiful and exciting, but when he does it with you, he may not feel that way, so when he does it himself, he is actually imagining it.

2, psychological reasons, or when you do it, let him not have that kind of excitement, or what kind of psychological shadow he has.
