That's a negative ghost rider.
If I can't taste you then the whole experience is lost on me. I'd probably go along with it if you said DATY was on the menu while setting up the date then you spring it on me that you use a dam. I won't do it again on the next visit or if you're upfront about it though.
If you're only comfortable with covered daty then more power to ya, I'm cool with CBJ but not CDATY. Just not my thing.
