These are a few things that I have learned along the way. I shared them with another board I belong to and quite a few of my friends had NO idea.
* Do NOT use lubricants. They will kill sperm! Use Preseed, it is sperm-friendly.
* Saliva kills sperm as well. It is best to avoid oral sex altogether during your fertile times.
* Don't clench! Immediately after BD, it is natural to clench your muscles, but you can push a lot of the semen (and sperm!) out. I have to force myself not to do this.
