Hi Folks,
In my experience I'd say the number of women who do actually enjoy giving head is well over half.
I'd go for around 70%. Maybe I've been lucky!
My lovely wife gets off on it massively. If I tell her how it makes me feel and how good she is at it (Very!!) then I can actually feel her shaking as she cums. Even talking about how much I want her to give me a blow job gets her soaking wet.
And yes....she swallows happily!! Even licks the cum of my cock after we've fucked.
As others have stated, she'd never really been much of a fan until she felt comfortable in a loving relationship. And now my BJ's are daily....
