Welcome to the forum. Thanks for your question.
You are no risk for HIV, for practical purposes, for the exposures described. Condoms work, and if they do not break wide open, protection is complete. (The idea of microscopic or very small leaks is an urban myth. I do not recommend inspection or filing of condoms with water to check for leaks after use.) Oral sex is very nearly zero risk for HIV, even without a condom, and kissing has never been known to transmit HIV, regardless of canker or other sores in the mouth.
From a medical or risk standpoint, therefore, you don't need testing for HIV at this time, except perhaps for the extra reassurance you may gain from the negative result. (At a personal level, if I were in your situation I would not feel a need to do it and would continue unprotected sex with my wife without worry.)
If your sexual lifestyle and choices are consistently as implied by the three events above, you can expect to go a lifetime without ever catching HIV. The only additional strategy I recommend is that you always ask new partners -- especially males -- about their HIV status and avoid sex, or be even more attentive to safe practices, with those who are positive (and not on treatment), don't know, or seem evasive about it. (You may do this now, but you don't say so.)
As for testing, I would advise you and others with similar lifestyles to pretty much ignore individual sexual exposures unless especially high risk, e.g. If a condom ruptures with an HIV infected or especially high risk partner. Instead, regular periodic testing for HIV and other common STDs (gonorrhea, chlamydia, syphilis), e.g. once a year.
Of course you are free to be tested at this time. If you do so, you definitely can expect a negative result.

I meant over the past month, not months. It hasn't been long enough yet to test for HIV
