Perhaps once he has paid yes but not before
I advised the op to "jump on her" but in the cold light of day maybe i was a little hasty?
Reading this thread again it seems that the op's definition of a regular differs from mine, I only consider a wg a regular if I've seen her approx 10 times & have no intention of stopping. If that is the case then i find certain rules don't apply & a little "jump on" (from both sides) is acceptable.
However the key point is that it is a lustful financial transaction and not love!
OP hope you sort yourself out & get back in the game, also be careful what you ask for on this forum as you may not always like the answer
