Regarding Breasd feeding

I am a married man, since last 3 years. B4 marriage i was very slim and have digestive problem. But 2 yrs ago, i wished my wife to Breastfeed me. Firsh she hesitated, then she willingly fed me regularly. Although, no milk comes out, but still by Suking her breast, helped my Digestion problem and my Health also improved. Everyone is stunned , but no one knows the Secret. Now again my Wife hesitate to Breastfeed me coz of some doubts in her mind. I have such questions pls reply me ;

Q 1) She thinks, by sucking her Breast, she may develop Breast Cancer & Suking may also enlarge her Breast size. While i studied on some sites, that this is even good for women to refrain from Breast cancer and doesnt enlarge Breast size. BUT i need your Medical Advice ?

Q 2) Moreover, as we planning for the Baby, so once she deliverd the Baby, After few Weeks Can she feeds her Milk to me as well? Does it may have any Harm on her health and the baby, by Feeding both at same time?

Q3) As some people say after delivering baby, women breast produce milk only for 2 to 3 Yrs, while, as per the Websites, if she feeds reularly, she can produce milk atleast upto 2o yrs. My Question, Is it True, if yes then untill what age or for How Long her Breast can PRODUCE Milk?

Q4) As mothers milk useful for Baby Growth, My Question, Is that milk useful for my body as well, Plus If my Wife Breastfeed me regularly for yeas, Does it saves her from Breast Cancer, and in which way her milk save me from Diseases or useful for my Health?

Q5) For Feeding me her milk for Years, Does it leaves any Bad effects on her Breast or Health. Does feeding increase her Breast Size.
Q6) LAst Question, How many time, easily she can Breast feed me in a day and for how long her both Breast can feeds me in one time?

Sorry, you may think, i may have asked quite a lot questions, Reason is, that,i am mentlly depreesed and confused as i got Habbitual of my Wife's Breast. Although, she is willing to Feed, but some doubts, so hesitates now, therefore we have asked you above questions, to get cleared.
