How about having a marathon session over the course of a weekend with your favourite clients? The goal: one orgasm for every year that you'll be turning. In your case, you're turning the big 40 (methinks you're soon going to reaching your prime

) - but I mention this option only because I'm thinking of you -- no self-interest here!
