I had sex last night and the guy took off the condom and continued; so I made him put one on and he said not to worry because he put one on before he came. Not so sure about that, like I know people have said that that's disrespectful and a jerk thing to do... not sure how I feel about it; but, I was wondering I noticed I have a small lump under my arm, er well I guess it's like in my armpit and was wondering if it could be like a sign of illness like an std or if it would take longer to develop whatever or what not? Should I be worried about pregnancy and stds even if it was a very quick or short time frame and he had not came yet?
