First, your priorities are misplaced. Assuming your casual brief relationship reflects your partner's usual

As you seem to already know, the risk of acquring HIV from any single episode of vaginal intercourse, even unprotected, is extremely low. Of course it would be higher if your partner is HIV infected or at risk, i.e. is bisexual or uses drugs by injection. Presumably not, or you would have mentioned it. But if uncertain, since you describe him as a friend, you should be able to contact him and ask. If the answers are no, you definitely do not need further HIV testing; indeed, if he lacks those risk factors, I would have recommended against any testing at all.
Bottom line: you need no further HIV testing after you get the negative result of your 6-week Home Access test. But you would be wise to have urine testing for chlamydia and gonorrhea. From the standpoint of statistical probabilities, the chance of a serious outcome is far greater from those infections than from HIV.
