I had sex for the first time with a guy but we did not use a condom. The guy told me he had not had sex before without a condom. He didnt ejaculate and it was too painful for him to go in far. The next day I had an itchy vagina and some light diluted blood discharge, similar to thrush ive had before. I was wondering if this was probably thrush after my first time having sex or whether it could be anything else.
