Discharge

Sometimes after sex my husband will have white discharge on the outside of the condom on the top side of his penis closest to his body (like near the condom opening) We know it's not sperm and we know it's from me, but for the life of me I don't know what it is. I don't think it's female ejaculation because that's suppose to be thin and clear, right? This is pretty creamy and sticky. Thicker than his stuff. Doesn't smell terrible, it's happened our whole sex life and isn't a yeast thing I'm pretty sure.
