You & your wife should consider a 5.5" circumference just the starting point...

I bought my wife a dildo last week, it is fairly girthy at 1.75" wide and 5.5" diameter.
1.75 inches wide would correspond to a diameter of 1.75" and a circumference = (2)(pi)(radius) = (pi)(diameter) = 5.5 inches.
Sorry to be picky about this, but a dildo with a diameter of 5.5 inches would have a width about 1.7 times greater than the distance across my knuckles, which even the most enthusiastic size queen might find hard to like.

I seem to recall that a survey, carried out by a company that manufacturers condoms (so they were motivated to get it right), found the average circumference of the cocks of college-age men is 4.5 inches with a standard deviation of about 0.5 inches. You can probably find it if you google "Cancun Survey." That implies that if men's cock circumferences have a "bell-shaped curve" distribution, about 68 percent of men have cock circumference between 4.0 and 5.0 inches. Thus, the 5.5 inch circumference of your wife's new dildo is somewhat fatter than the "high end of average range," but it's certainly not gargantuan.
I suggest pointing this out to your wife, and mentioning that if she wants to "keep up with other women" (keep up with the neighborhood women, so to speak) in terms of ability to fuck men who are well hung, she should definitely practice and become accustomed to using her new dildo.
To assist your wife, thereby helping her to "keep up with the neighbor women," you might consider lubricating her new dildo well (with, for instance, Astroglide), then kissing her thighs and licking and sucking her pussy (on your knees with your head between her legs while she relaxes in her easy chair, for instance), then... when she's wet and well-lubricated... gently pushing her new dildo into her pussy, stopping as soon as she says it feels uncomfortable. Then, continue sucking her pussy until she orgasms. Push it in a little farther each time you do this, and try to persuade her to let you do this once a week, gradually increasing to 3 or 4 times per week. (Once a month isn't sufficient for her to become accustomed to her new dildo.)
When your wife becomes accustomed to taking her new dildo and allowing you to regularly pleasure her to orgasm with it, which shouldn't take too long, you can buy her a larger dildo that's both longer and has a larger circumference, say 6.0 to 6.5 inches. In this way you can gradually introduce her to the pleasures of big cock sex, while also enabling her to become accustomed to you being her cuntsucker in association with her "big cock sex" pleasures. (You should, of course, purchase vibrating dildos to increase her pleasure.)
