Hi doctors so I'm a bisexual male with a girlfriend. I have had a few encounters of unprotected oral where i was the giver let's say about 5 encounters over five months. 2 times resulted in semen in my mouth. I also had a few encounters with protected anal as the giver. Since these encounters i have had very bad anxiety regarding hiv.  What are the chances i acquired it from these events 

Welcome to the Forum. Thanks for your questions.  I'll be glad to comment.  Your risk for HIV is not zero but it is close to that.  Congratulations on your consistent condom use for your highest risk activity, insertive anal intercourse- as long as the condoms don't break, your level of protection is excellent. the risk of oral sex is very, very low.  To help you with your assessments and moving forward, the levels of risk for HIV acquistion for various unprotected sex acts if a partner happens to have untreated HIV are as follow:---

Okay thank you doctor would it be okay to resume unprotected sex with my girlfriend and have you ever seen a case of hiv come from only oral sex

I have seen a case or two which appear to have been acquired from performing oral sex on untreated HIV infected persons- these persons had many, many partners over a long period of time.  In your situation I would not be worried.  I would not hesitate to have unprotected sex with a regular partner.  One follow up remianing.  EWH---

Okay because I'm scared to get tested. If i continue to approach sex the way i have can i expect to remain hiv negative so unprotected oral and occasional protected anal
