If you do not have desire or passion for sex can you still get pregnant?

Why would you think that even matters?

Of course it has NO bearing on it.

I highly recommend you get human reproduction education from someone who knows something about it... and not whomever told you that lie.

In fact... don't believe anything the person that told you that says.

You get pregnant when a sperm fertilizes an egg. A woman's ovulation has nothing to do with their sex drive. If a penis is inserted and semen is released and a sperm fertilizes an egg then pregnancy results.
