Do girls have semen like guys when they climax?

Yes. It is a creamy fluid that comes from deep up in her vagina.

Some girls can even squirt when they orgasm. This is a different fluid, very clear and thin. It comes from the gland that give moisture to urine. It isn't pee, it's the liquid her vagina uses to flush out the pee. It is pure and sterile and doesn't stain or smell.
