I am a 18 year old female. I was talking to my frined about getting into a relationship which i knew him for 3 years. I had sex with him one night without a condom, the next night after we had sex i went pee and it was burning, he came over the very next night, and i was rubbing on his penis and i felt something dry, so i turned on the light and i looked and i noticed he had bumps by the top of his penis head and when i lifted up his head i seen scabs and bumps, i asked him what they were and he said the doctor told him it was from him masterbating without lubricant. I told him i did not want to have sex the second night. Iv never known it to look like that which i am very SCARED. If he has any std is it possible for me to get it for the time without a condom? Please help
