HIV through Oral sex

I am a bi curious male who pretty much only dates women and has a curiosity for male / male sex. I've explored this very minimally and only with a few different people. My experience and curiosity are only in performing oral sex. I've done this a couple of time very minimally ( maybe a minute) and once for an extended period of time. None of these experiences resulted in ejaculation in my mouth. I am concerned a little bit because I occasionally have bloody gums. I have not been able to get a clear answer as to whether performance of oral sex is at all a risk or not. Any thoughts would be welcome.
Thanks.

You were never at risk of contracting HIV from oral sex. Use condoms for anal and vaginal sex and you won't have HIV to worry about.
