Q: I love the butt plugs with the tails and I'm just getting my wife comfortable with anal, is there anywhere in particular that you get yours and are they comfortable?

Sir here:

I recommend starting small and having a ramp plan with beginners. I’ve found this to be a good ramp progression:

Small Starter:  Cal Exotic BOOTY CALL BOOTY ROCKER BLACK
http://www.amazon.com/Exotic-BOOTY-CALL-ROCKER-BLACK/dp/B00GIXCQUU/

MED:  California Exotic Novelties Booty Call Booty Beads, Black
http://www.amazon.com/dp/B00725VCKI/

Bigger: Tantus Neo Anal Butt Plug, Black
http://www.amazon.com/dp/B00AG591PO/

For tails the crystal delights plug tail size is a good smaller size that is still big enough to stay in:

Comfort is of course going to be relative when it comes to anal :) but all of these designs are smooth without any extra irritating features.
