I agree with kana in that if you're going to enjoy the booty calls etc that hopefully you're practicing safe sex - this is even MORE important if (when?) you get a transplant as you have to be super careful in this regard (HSV1 - ie: herpes simplex - can be very bad for transplants).
However I digress from the main point.
Kidney failure is no fun. We all know that, and it affects many things. Heck, I'm amazed and somewhat envious that you appear to have this awesome sex life while dealing with dialysis - I just didn't have the energy for it!!
You're asking why you have to go through the hoops to get approved for transplant? I'll tell you why. transplantation is a very special gift, and rare enough that it is valuable to us. The doctors and so on want to ensure that a) your body is able to accept a transplant and b) your mind/attitude is ready (in terms of being compliant with the medication schedule, and being able to look after the transplant once you have it).
Is it worth it? I've only had mine for 2 months and I can tell you that YES!! It damn well is worth it. I feel so much better (and of course, no machine!!), have energy to burn, and well don't mention sex because... well.. let's just say that I'm ready!!!!
However it is a huge responsibility and one to not be taken lightly. We also have to remember that transplant is another treatment option and comes with its own pros and cons. It is the most IDEAL form of treatment for most of us as it frees us from the machine and allows a mostly normal life and that is so awesome I can not begin to describe it - even in the short time I have had my wonderful gift.
I guess it's up to you - continue to deal with dialysis and hate it or work towards being approved for transplant and the goal of being able to live that more normal life. It's up to you.
