I'm worried I have an std, recently I swallowed my partners sperm and ended up with tonsillitis, I've read that it is possible to get tonsillitis from swallowing infected sperm, a few weeks later I had sexual intercourse with him for the second time although the first time was very brief,and I bled a fair bit straight after it, I also bled lightly for the following 2-3 days, it happened about 4 weeks after my last period but usually my period is irregular and the bleedding didn't seem like my period, I am only 16 and I know Im quite you're bit I am worried, if I do have an std is there any way to cure it? Thank you.
