Well, if an MPA happens to fall in love with a client, she should keep that to herself..You will not believe it unless and until it happens to you. They may be "professionals" but they are also human, as are we. It has not happened to me, but as others relate here I have made some very good connections with SWs, to the point that I would really enjoy their company even if no sex was involved. Respecting and treating people well often (but not always) pays off.
Just can't see an MPA saying to a client.."You know John Doe1, you're the only one who can make me cum and I just love being with you...I want you to have my babies cause im starting to fall in love with you" Nah I just can't..lol
