Welcome back to the forum. But with all due respect, it is not the purpose of this forum to provide psychological counseling, especially when someone recognizes his or her own inappropriate and irrational fears. The level of anxiety your feel about HIV and other STDs despite your intellectual knowledge that the risk was minimal to zero is not normal, and both the compulsive testing and your need to seek our support also indicate a mental health problem that needs attention. A forum like this is not an adequate substitute for that and we cannot provide that service.
The odds are strong that your new partner doesn't have HIV. But even if she does, the direct answers to your questions are: 1) No. 2) No. 3) Possibly yes, but oral sex is almost zero risk for HIV and low risk for other STDs. 4) Yes. 5) No risk. 6) 100% protection against HIV and most STDs, less complete protection against herpes and HPV. 7) Too complex a question; do your homework by reading other information sites. 8) True; even the baby often doesn't catch the virus. 9) HIV can be transmitted during the window period if there is an unprotected sexual exposure. All these questions have been discussed many times on the forum; use the search link if you need more details.
Please seek the psychological care you so badly need. I suggest on it out of compassion, not criticism. I will be happy to take a brief follow-up comment/question after you have obtained that care and report back on the provider's advice and the treatment you are under. Until then, no comments will be accepted and I will have no further replies. Finally, please note that MedHelp permits no more than 2 questions every 6 months on the professionally moderated forums (see Terms and Conditions).
