You're welcome, BJ! It was really no problem because I have researched this in the past and saved the links. Your wife is fortunate to be comfortable enough to give this a try, and she is also lucky for you to be interested in exploring such a creative way to enhance her pleasure and to research how to do it right. I feel like I have to tell you some more stuff you might already know, but is too important not to mention in any discussion of a topic such as this one:
I think you will both get the most out of this if you just make sure to keep it a sensual and spontaneous activity, not just a routine or scientific procedure. (Then again, some women do get excited about a more clinical, scientific atmosphere as we have seen, for example, on this forum, so I'm sure you will find whatever approach she enjoys the most.) If you can keep this a sensual and spontaneous little indulgence, just a supplement to talking, kissing, etc, you may not have to get her to agree to a three month regimen because she will already be looking forward to it every day. It's not so much talking her into it as it is allowing her to associate good feelings with it, which is inevitable if you just let it happen. The key is to take the opportunity for this to become a special treat for you both. After all, the instructions suggest that the woman should be nice and turned on in order to be ready for the pumping session to commence and to proceed most effectively and enjoyably.
I would not recommend trying this for 3 straight months in a row, however, if that is what you meant- remember to take a day or two off every week or so. I also just read that the device should be pumped up and left on for no more than 10 minutes straight, but if you remove it and wait, I'm assuming, at least another few minutes and put it back on for another 10 minutes, is fine (says so at the bottom of this other page- http://www.femalecd.cyberspacedoctor.com/pussypumpcylinder.html ). In this case, even if you are only leaving it on for one 10 minute session for the first few weeks or months, I would recommend spending more time before each session just generally getting your wife in the mood, then a few minutes warming up with the pump by doing a series of brief, subtle pumps on lower pressure before you pump it up all the way (still on a pressure lower than 5 units) and leave it pumped up with the cup on for the 10 minutes. Takes a bit more time to get going, but the whole point is to give her a chance to appreciate this as much as possible and look forward to it. So maybe still do whatever affectionate things you do to get warmed up for the pumping even on days that you take a break from it, without ever designating to her whether the pump will or will not be used in that session. I believe it also helps to make sure she keeps in mind that this particular activity of pussy pumping is just another way you are showing your appreciation for her, and not something she is obligated to do for you. This may seem obvious to you and her, but I just thought it was important to mention just in case. (sorry for such long reply again!)
PS, don't use stop watches or timers and alarms or anything. That seems like it may be a mood killer, all the beeps and the risk of looking at the watch more than her. Just glance at the clock on the wall/bedside table every now and then to keep time
