Sex with a condom on two occasions used condom both times but second time the condom wasn't all the way at the base quickly fixed. hiv chance????

No risk, no worries: Condoms often slide on the penis during sex, and it is normal for skin above the condom to contact a partner's skin and genital (or anal) fluids. As long as the head of the penis and urethral opening are covered during penetration, and semen doesn't get into the vagina, protection is complete against STDs transmitted through genital fluids, including HIV, gonorrhea, chlamydia, and viral hepatitis.

Condom use: If the condom was used prior to ANY form sexual activity which includes oral sex, then your chances of HIV are minimal. The greater question is, why is sex an option at all if you are concerned about the HIV status of the partner? Sexual activity should be between two people who know each other well enough to know their HIV status prior to sharing "bodily fluids"
