My wife hasn't swallowed my cum in nearly 13 years, not even tasted it or put it to her lips. Doesn't enjoy mine, she just doesn't get horny enough with me which she needs to do. She does with our friend though, more so if he's cum on her tits or belly and she'll play with it, usually then licking her fingers etc. but i've only seen a gent cum in her mouth once in 13 years. She said she loved it as a teen and early 20's, but 10 years with her ex-husband insisting on BJ's nearly everyday sort of killed it for her.
