Re: Will women ask for oral sex?
I don't have one, my wife hated it until about a year or so ago as well. Honestly for the first 8 years of marriage I'd get lucky to get one a couple times a year.
Then, she hit 30 and started REALLY liking sex in all forms much MUCH more and started "branching out" (toys, new outfits, etc). She is the one that just went through a libido change.
Have your wife try good mints, if its the taste she doesn't like (most women who don't like), my wife gets mints from Ambiance (look them up online, its a chain store for 'lovers') that are specifically for oral.
Since she started using them and was able to get over the "taste" she has really started to enjoy giving it.
