Is this common?
My wife and I have been together 15 years and have 2 children 7 and 10.
Previous partners have all loved me giving them oral sex, and I quite liked doing it for the obvious pleasure it gave them.
The wife (then girlfriend) tolerated it at first (so it transpires) then told me it did nothing for her and never has. We haven't even tried it for years now. She swears that it has never done anything at all for her even with previous partners - and she has had "a few" so she has no hangups about sex in general.
Don't get me wrong, its not a big problem, just wanted women's viewpoints on it as it seems to be a bit unusual and I have a vague feeling she (we) may be missing out!
