Interesting topic, great that you brought it up. I imagine that some of the answers will be influenced by the particular circumstances of the players involved. In my case, my partner and I are 1000 miles apart and we get together every 3 to 4 months, on average, for 5 or 6 days at a time. Due to other obligations, we've hit a real dry spell recently and haven't been together since November, and probably won't be until July. Lord willin' and the creek don't rise!
For us, there is no such thing as a quick exam. Because we are so far apart, and because there is so much time between visits, we have the opportunity to conjure up some really elaborate schemes. We even write roadmaps of our scenes together. I know that for some that sounds a little "anal", but he is an engineer and we're both control freaks, so that's what works for us. All that advance planning is a form of foreplay and serves to keep all the mechanics functioning in top form.
When we find something that really, really works for us, we tend to incorporate it into many of our scenes. "Repeat as needed". Our play sessions always begin with a thorough head to toe examination. In a way, it draws out the anticipation and helps both of us to get comfortable with being together again after a long absence. Usually the first day is devoted to exams, and after that we get into treatment and procedures. No matter what we do, we have a great time!
Gosh, I sure do miss that man!
