At present my wife & I are in relationship therapy due to my obsessing over the need to recreate a memorable voyeuristic experience from my late teens. Prior to this, and for a long period afterwards, this was my only rewarding, fulfilling sexual experience against a few that were pretty bad and recent events have caused me to fixate on it to a degree. It's been determined that this is a massively significant occurence in my sexual life and has subtely/unconsiously informed several of my decisions and sexual wants since, including within my marriage. The therapy has helped me understand where this fixation has come from and I'm thankful for it, even though it has uncovered quite a bit of suppressed anger, resentment and unhappiness. It's getting dealt with and I'm already feeling more balanced and happy because of it. I hasten to add that that neither the original voyeuristic experience nor what I want to see recreated is in anyway problematic from a legal or moral view (seeing two girls genuinely kiss - not for titilation purposes, and wanting to see two women actually have sex respectively. Neither of the women I want to see will be my wife).
My wife has also uncovered a couple of self-esteem issues that she's working on and she too is making progress with them.
The dillema is this: I've been wanting to see the recreation described above as it has been a recurring fantasy and a happy memory that has seen me though some bad times in my marriage without my ever resorting to an affair, extra marital sex of any description etc. My wife was unsure as to whether to permit it, and has been counselled by our relationship counsellor not to do anything she is either unhappy about or doesn't want to do - for obvious reasons. She's agreed today that I can do it, but her reasons are mostly around her not wanting to see me unhappy and also a sense of thanking me for my support in during the bad times (her depression etc). One half of me wants to selfishly leap at the chance and just go for it, and the saner more considerate side thinks that whilst I appreciate her reasons, they're more "why not" reasons than "I want to too" reasons. Or to look at it another way, a lack of negative reasons does not equal a single positive reason. Am I over-thinking matters if, as I am at the moment, am not accepting her yes decision on the grounds that without her actively wanting to allow me to fulfil the fantasy, it could possibly harm her self esteem further? Or should I not be looking a gift horse in the mouth, accept the offer and just be sure I'm offering enough support and reassurance that if she feels in anyway awkward about it, we can either try and resolve the issue or call the whole thing off (massively dissapointing as that would be to me)?
Apologies for rambling on. I'm not neccessarily after advice per se, more opinions that aren't second and third guesses of my own.
