Vernon Kay - Selfsuck Rumour

He's a bit full of himself and a bit of an egotist so while he may be hung (who knows) I think the self suck comment was an attempt to big himself up.
 
I am sure his lovely wife would do it for him - I cant believe he would have said that on the radio but good for him if he did!

Maybe he is letting her sore jaw take a break...
or he needs it so often that one mouth isn't enough and he is being faithful by not finding a stranger's mouth.
