Why haven't my husband ask me to give him oral sex . Its not like him.

Have you asked him? We don't know what's in his mind.

Ok, what a list of a 100 possible reasons ? No one here could even guess why YOUR husband does not. Perhaps you always complained about doing it and he got tired of hearing you complain? Perhaps he did not like they way you did it and would rather just not do it.

Perhaps you should just ask him ?

He's your husband. Ask him!

Some men don't like oral. Some men don't like asking a question that would most likely be answered no. Some men...

Ask him.

Like others have said... ask him... besides at least in my experience... I don't expect women to ask me... or that they should expect me to ask them. If you fell like something just do it or mention it... they are your spouse after all.
