The odds that you contracted a std from oral sex are rather low in general. The odds that you contracted hsv2 or hiv are so low it's not even worth testing for. As we discussed in your previous posts on this , odds are you didn't contract anything and if you had contracted hsv1, you would've most likely had a "classic" ob and known it by now.
Honestly I don't recommend any testing at all from this.

There is absolutely no way to quantify that. Rest assured that you are much more likely to not catch anything than you are to catch something. Wait 1 week and get tested for gonnorrhea and chlamydia. Wait 3 months and get an hiv test and an IGG HSV 1 and 2 test. Stop having unprotected sex with strangers.
Good luck.
