Welcome to the forum and thanks for your question. Congratulations for a rational approach to your new relationship and your conscientious decision to be tested for HIV -- as well as for other STDs, please.
You needn't be at all worried about HIV. Asuming your sexual history since 2008 is accurate and complete, you indeed practiced entirely safe sex and the chance you are infected is virtually zero. In addition to the safe practices described, HIV is more rare in women than you seem to think; probably none of your partners was infected. To your specific issues:
1,3,4) HIV is not transmitted by hand-genital contact and has never been known to be transmitted by cunnilingus. If it's transmitted at all from mouth to penis, it is so infrequent that you could expect to receive BJs from infected partners once daily for 25+ years before there might be a significant chance of infection.
2) Condoms aren't perfect, but they are highly protective -- and as noted above, most likely none of these partners had HIV.
5) Shared razors are one of those theoretical risks, listed on many websites and other educational materials, but probably zero risk in the real world. To my knowledge, there has never been a proved, reported case of HIV transmission in this way. You certainly aren't going to be the first!
So neither of your most serious worries should be a worry at all. Go ahead with HIV testing as planned, and also ask the doctor or clinic to do a urine test for gonorrhea and chlamydia and a blood test for syphilis. Don't lose any sleep at all waiting for the results -- I expect all of them to be negative.

Thank you for prompt reply.
I didn't ask STD related questions because I didn't wanted to break the rules:) I haven't seen any obvious symptoms (sores, pain while urination or outbreak of herpes lesions) so I wasn't worried about STDs. Also, last year the primary care physician gave me "z pack course of 5 days" for bronchitis and I thought that antibiotic that strong would kill any STD bacterial infection.
Anyhow, you're right thought. It is wise to get tested for them anyway while at it.
Again thanks the prompt reply.
There are no rules against STD questions on this forum -- just that non-HIV STDs shouldn't be the main focus of the initial question.
It is true that a 5 day Zpak would prevent or abort almost all bacterial STDs to which you might have been exposed. Following such treatment, I no longer see any need for STD testing, except possibly for syphilis (which conceivably could go back to a distant sexual exposure, and because longstanding syphilis might not be cured by that dose).
Just wanted to give you an update. I did the urine test for Chlamydia, Gonorrhea and blood test for Syphilis through LapCorp Services (quite expensive $229 value for testing of the three). All three came back negative non reactive.
Haven't gathered the courage to test for HIV yet but I'll do that in coming weeks.
Your insight and comments were really helpful.
