It's not just the visuals that make them blush.
In talking with some receptionists and insurance adjustors, having to describe what I needed or "exactly" what an IPP is in laymens terms you can hear the "redness" in their voices as they stammer; "" Let me get you someone who can help you better than I can" !
Hearing words can have an equal effects as seeing. You cannot always tell who it is youre talking with on the phone by the sound of their voice.
In talking with one especially sweet sounding insurance person I explained if she was uncomfortable discussing the topic , I respected that; she could feel free to pass me off to someone else because I have talked about IT so much its second nature to me.
To which she responded as she chuckled, that she was married for 48 years, ..had 5 sons and 27 grandchildren and there wasnt much she wasnt comfortable discussing.
That lightened the mood.
This is especially true as you gain more & more comfortable talking about implants and showing your junk off to different doctors, nurses, technicians etc.
