Dominatrix question

Hi all,am by no way new to escort scene but new to dominatrix just have a few questions if someone can help me out with .
I have a fantasy of feet worship and pussy/ass worship do doms offer this or is it not a sexual contact thing .
Also do doms sexual releave their subs at end of session.
Or would I be safer looking for an escort to offer this service ?
Any guidance would be appricated and any reconmondations
Hope someone can guide me in right direction thanks
