Possibly or maybe I’m just used to LH ways of measuring as that’s where most my toys are bought from 
I can see why diameter would be more useful really.
Ah that’s interesting, Thanks for clearing that up for me 
Oh I see, my mistake I thought you were wanting a realistic one. But it’s only if your wife orders it, if she were to agree to being your mistress?
Yes I agree, depending on the fantasy/desires it may be best to just discuss a little bit at a time rather than reveal it all at once and risk scaring them
