A week-long getaway, perhaps...but an appointment where you get to take your time, have dinner, after-dinner pleasure, and then fall asleep with your companion isn't something that needs a more thorough vetting process than a 2 or 3 hr appointment.  It's pretty much how one night stands play out in the civilian world.  

My advice:  If you find a girl that tickles your fancy, go for it and have a good time.  Being *too* risk adverse can kill then fun in this game we all play.
