I develop very strong feelings for many of my clients. At a practicum site, we had a running joke about adopting kids who had horrible home lives because the paternal/maternal feelings that this provoked were so strong. Sexual feelings are just another part of what occurs during therapy. Our ethics professor, who had been on a licensing board, really emphasized the importance of dealing with counter-transference and self-care to prevent going down that road.
On another note, you don't have to date patients. People love to talk to someone who is a good listener so I would think our skill set gives us an edge in that realm. Of course, that also means most of us are in stable relationships so we don't get to try that out much! My own smoking hot wife hates that when we go to a social function, invariably women will be talking to me about psychology. Of course, the men love to chat with her about anything at all. 😉
