Welcome to the forum.
As you were told on the community forum, this was a no-risk exposure for HIV and other STDs. Condoms work, and it doesn't matter how they are removed after sex.
The standard HIV blood tests like the one you had are completely reliable 8 weeks after exposure. You don't need another test. Here is a link to a thread that explains why a 3 month test is often recommended, even though earlier testing is reliable:

The ProbeTec test for gonorrhea and chlamydia is done on urine or a urethral swab. That test is valid any time more than 2-3 days after exposure, so you can be sure you don't have either of those STDs.
I hope this has helped. Best wishes-- HHH, MD
