Whilst I acknowledge other points I have to vote for 'no'. Rape is a forced non consensual act - non payment of services should not effect the fact that at the time it was consented to.

If the decision was that it was rape, where is the line drawn? Is having sex with your partner in the mistaken belief that they love you/behave in a certain way/like certain things/promise things rape at the future point you discover they have lied? How about after a relationship breaks down and love disappears - was some sex rape, and other sex just sex?
