Braxton's quickie for the day...
Email: My wife and I have a mutual stim once or twice a week. I use prostate stim, so there's no way that I can finish before she does! I would like to start my stim about a half-hour before her, so that we can finish about the same time. This is because I find it a big distraction when she finishes before I do. She has a problem with this because she insists that we start together. Could you please consult The Stimmer's Etiquette Guide and let me know the polite way to resolve our problem?
With more and more stimming couples, an Etiquette Guide might not be a bad idea at that!
Since the operative notion here is "mutual", it's my opinion that you both need to be flexible on what it takes to maintain an atmosphere of togetherness. Start your stim together, and stay together until both of you have accomplished your "mission".
Might I add, considering the far too many couples who have completely quit on keeping sex alive, yours is indeed a refreshing problem!
