I used to have orgasms all the time during sex and foreplay. Recently I just stopped having them. Why? We have been trying everything.

That is the reason. Your trying way to hard. The harder you try. The less likely of it happening. Plus once you experience something for so long. Your body needs a break. You can not expect it to happen every single time, and when you expect it and it does not happen. You get so worked up it will prevent you from experiancing it further.
