Haven't ejaculated in 3 days. Will my pre cum have sperm in it?

Here are some... Pre-cum contains much fewer sperms usually at the level of posing no odd to conceive. But don't count on such; instead, gear up due diligence and vigilance to practice safe responsible sex with currently available methods. More on the related subjects? Seek counsel to gain higher standard of safe sex than the present.
Maybe. Although most pre-ejaculate fluid has no sperm it is possible for small amounts of sperm to exit your reproductive system and find its way into the precum or pre-ejaculate. It's therefore possible for this to lead to a pregnancy. If you want to discuss your sex life with me further please set up an online appointment with me.
