Certainly not as when younger... It seemed in the past, that there was a need to have the orgasm, as a Finale of sorts, to release many things, stress, Blue Ball pressures, pent up sexual energies, etc.
As in the past three years, the experience has changed in so many ways. The dynamic has changed greatly in that, my dear friend has come to deeply enjoy stimulating me anally for longer & longer periods (as in 2-3 hours) duration whereas our sessions used to be a matter of 15 minutes or so... with results.
Back then, the anticipation had me 1/2 way there to orgasm/ejaculation before we would even begin. After literally 100's of trials & errors figuring out our mutual needs and communications in this rather DEEP activity, we found that either of us could end up exhausted after longer & longer sessions and totally satisfied, with no release of orgasmic fluids having been released.
We are still trying to figure it all out together, each time being very different from the previous. The best part of this all, is the fact that we never expect or anticipate any sort of outcome and therefor, we are never disappointed with our results.
Just blissful peace and calm each time. So sometimes, yes we do both CUM during our session of lovemaking, but most of the time, No.
And it is beautiful always! In our 60's and 70's now, we feel most fortunate indeed.
