Again, I'm hoping you fellow TFPers can come to the rescue as you have done many times in the past.

Been with the (now wife) for over 5 years. Everything is great...we get along...have fun...except for our sex lives.
Don't get me wrong....4 out 5 times its great sex, because well...its sex. But that 1 time out of 5 is what sex really should be. tons of foreplay, bust out the gadgets like I was James Bond, so on and so forth. But that only happens once a month or once every two months. All the other times its just a quick bang bang and go on with our days. This happens once a week if im lucky but usually once every 2 weeks.
Anyways....I've noticed that when I don't get some loving I become distant and she knows this too. We have discussed it hundreds of times and after the discussion, we have our fun. The next day there may be some fun again....but after that its back to once a week or once every 2 weeks (if I'm lucky).
I've gotten to the point where when she asks "whats wrong" I just say "I don't want to talk about it". and it boils me up inside. Because I KNOW she knows whats wrong because besides the no sweet sexing...we have a perfect relationship.
I've sort of given up talking to her about it because like I said...its been done hundreds of times. Its like I'm wasting my breath.
So my question is this.....are there any over the counter or even prescribed things that will lessen my libido, by A LOT?
I think this may be my only alternative because if I'm not horny and don't get any....it won't cause me to boil up inside.
I'm really tired of talking aobut this every 2 months with her and this has been going on for over 2 or 3 years and its always the same...its like beating a dead horse. We talk. We get down for a day or two...and then its back to nothing.

So......any advice on any of this is greatly appreciated, but some suggestions on something to keep my libido down would be really really appreciated.

Thanks in advance.
