Me and my girlfriend decided we want to do anal, but she recently told me she had a boyfriend who she did anal with, but it was the first sexual partner for both of them. She doesnt show any symptoms, and said she didnt bleed during the anal. But i really need to know, what are my chances of getting an std, I dont think he had one, and i feel too young to buy condoms, and we want to do it without them, is it safe? Please help.
