I have always used protection for all my sexual activities but I am engaged to an amazing man and whenever we have sex I sometimes let him cum inside, . I noticed after several times I would always get this itchy burning sting throughout my vagina and the walls. Id have to hop in the shower and rinse everything out right after my orgasm. It was extremely uncomfortable and I found out later that some women are allergic to sperm. Im also allergic to the spermicide on most condoms. Anyone else have any issues w sperm causing pain?
