Sperm either hasn't been found in precum, or has been found in the thousands (low enough to consider it infertile) and also appeared to be immobile. Why can't people get it's just a lubricant or, worst case scenario, a carrier for sperm from a previous ejaculation that hasn't been flushed out? It's not rocket science ffs...
