First of all, try not to worry. I can't tell you how many times I have patients worried about small bumps that they happen to notice after a worrisome exposore or sexual encounter and it turns out to be nothing. Small bumps on the penis like you are describing are often called "milia" and are benign and normal. They do not indicate an STD at all. They can come and go and sometimes people will notice them more after lots of friction or rubbing. It would be extrememly unlikely for these to be the beginning of warts or HPV. However, if they get bigger or start to look like warts, that is a possibility and you should get checked to make sure. Based on what you are describing, however, I think the more likely thing is that these are milia, so they will just stay that way or eventually go away, and it is not a disease or anything transmitted sexually.
You should still wait about 3 months before checking for HIV or Syphilis or Hep B, especially if you had a recent negative exam you don't need one sooner. To get checked for Gonorrhea or Chlamydia you can get checked 1-3 weeks. If you are super worried you can get checked in 1 week, then again 4 weeks later. If you are negative both times, then you don't have those STDs. Pretty uncommon for either of those to be in a person's throat, although the risk is slightly higher for Gonorrhea. It is still extremely unlikely that you got anything from her throat, and the recommendations about getting checked are the same: 1 and 4 weeks.
The fact that you are both caucasian doesn't change the fact that your risk of getting anything is really really low.
Please try not to worry so much! I really really think you are getting too stressed about this. Think about worst case scenario- if you got an STD however unlikely
that would have been, then it was probably something common like Chlamydia. I think you have way less than a 1 % chance of getting this, but lets say you did. You may not even get symptoms, but if you test positive then you will get antibiotics (that you take that same day, only once) and then THAT'S IT! You are cured. You need to not have sex for 7 days after the antibiotics. I am not even going to give an example regarding the chances you got HIV because if you got it with only a .0001% risk of getting it, then you should play the lottery because those would be really crazy odds! So please- try to calm yourself down. Remember:
- You probably didn't get anything
- If you did it is most likely an easily curable STD
- But you still probably didn't get anything
Try to do some breathing exercises, stay active to get out all of your worries, and get checked in 1 week, 4 weeks, and again in 3 months (just for the blood tests then).
Let me know if you have questions. Bu try not to worry
