well...i think ultimately the dancer can/should evolve to the point of experiencing that connection with *himself or herself*...to learn how to dance freely and blissfully "for oneself" on a level, which means then that you can be present to *anyone*, if that makes sense. it's no doubt common to identify the emotional connection one feels with one's instructor (or other partner), but truly, what lies beyond that IMO is just generally being completely present both physically & emotionally, no matter who is around. any emotional attachment to a pro or a partner is sort of besides the point...tho it certainly doesn't seem that way when it occurs. i look at great dancers -- my own pro, for example -- and see that they can be fully connected, fully present emotionally, but it's not necessarily to the person they're dancing with. they're just fully present in general, with all their sensing faculties *on*. they are just so alive, and that aliveness can be very igniting and transformational to be around. so....no prostitution. rather, a lovely example of what it's like to be fully present both physically & emotionally. IMV.
