Perhaps not such as easy question as it depends very much on the lady.
Oral is nice, but I sometimes find deep throat uncomfortable especially if teeth get in the way,
sometimes I wonder if my cocks going to be bitten off, which is why of course I am always respectful to my escort!
Sex can also be fantastic, but not with a lady who says she cant take all my cock which can be a big turn off
(I'm only average by the way).
Therefore it depends on the individual escort.
Not so good if you have a husband or boyfriend in the toe!!!
