Haven't tried.. just read about ....?

I think I would be leary too. I just researched it for you and apparently there's some type of lubricant that is safe. It's called Pre-seed. Try preseed.com. Also, the bacteria in saliva is not good for sperm so I guess while trying to conceive is out... idreamofbaby.com. I also looked on babycenter.com under fertility and lubricants. Don't try baby oil.
