Some additional comments. I think your wife looks promising....
John101,
In retrospect, my reply above seems overly brief. Sorry about that. To enlarge somewhat: your wife is on the right track. If she has told you she wants to take lovers ("just as an experiment," of course), and is pushing you to accept her need to do that (oh-so-gently, no doubt), she has — I would say — already started you down the road to becoming her cuckold.
For a view of what it's like from a woman's perspective, you and your wife may want to read the extended thread that starts here:

which is unusually good. For a view of what it's like from a man's perspective, see the extended thread that starts here:

and continues here (to the present):

For an unusually comprehensive discussion of the significance of cock size (written by a woman), I suggest you and your wife read the thread that starts here:

As an aid to assisting your wife with increasing her stature to cuckoldress, I suggest you and she read the 8-part article that starts here:
» A Wife Into A Hotwife Hot Wife Blog - hotwife and cuckold husband fetish discussion
I would also suggest referring your wife to this "e-zine" (which I recommend to you also):
Scandalous Magazine cuckolding, fashion, beauty, health, sex advice for women
It may assist her with recognizing that what she wants is not "weird;" rather, there are lots of married women who have made their husbands their cuckolds and consider that an optimal way to live. As one wife put it (elsewhere on the web, in a word of advice to women): "Making your husband a cuckold is among the most satisfying rewards available to you as a married woman."
I hope the above threads and sites answer some of your questions, and help with getting you and your wife started.
Please thank her, on my behalf, for allowing you to post her picture. She looks good.... very nice. Since she allowed you to take her semi-nude photo and post it, I would say she shows good promise and appears, in essence, to be already on her way.
Best wishes to both of you—
Custer
*BTW, Nimrod has given you some good advice (in his last sentence, above).
