You did not experience a risk for HIV from the exposure you describe. As long as the head of your penis was covered, you were protected. Condoms also protect from Gonorrhea and Chlamydia, not sure why you were given an antibiotic for Chlamydia?
Further, condoms are designed to fail catastrophically if holes or tears are present in the material. You would have known had the condom broken.
And, lastly, vaginal fluid cannot leak under the condom as long as it was used correctly, and you withdrew while still erect.
Well my symptoms were pressure in my Lower abdomen and odd feeling in my urethra and so I guess givin the situation I was prescribed a single does of antibiotics ... That's what scares me if another std was able to infect me
This wasnt in the original post but
I also had a small cut on my finger and didnt realize until after that I fingered her with that finger ... The cut was still red but was already scabbing over was this also a risk ?
