Okay. This is a bit crazy. But I was just doing some TTC research and came across this:

"The researchers also looked at four oils found around the house: canola oil, sesame oil, mustard seed oil, and baby oil. The results of sperm motility tests with these possible sources of lubrication were very mixed. Canola oil and baby oil had no effect on sperm. Sesame oil drastically reduced sperm function. Interestingly, mustard seed oil, which researcher tested because sex workers in some parts of the world believe it kills bacteria and use it as a lubricant, made sperm hyperactive for over an hour. The authors suggest more research would be needed to confirm and explain this result (and perhaps to see if it could be used by men having motility issues)."

Here is the research article itself: http://www.fertstert.org/article/S0015-0282(13)03456-0/abstract?cc=y

Anyone wanna try using mustard seed oil this month and then come back and tell us the results?
