I am all in favor of an open discussion about the risks here, but I think it is important not to give people bad information or minimize the risks.
What I have read about oral sex is that there are documented cases of people being infected with HIV from oral sex, meaning, the receptive partner was infected from semen in the mouth.
Receiving oral, from what I understand is very low risk, in that saliva is inhospitable to the virus. I couldn’t find any reported cases of HIV transmitted by receiving oral.
Vaginal sex is a different matter, and I disagree with what you say here:

it’s very difficult to get HIV from a female through only vaginal intercourse, almost most links will tell you the same, most of intercourse transmission is through anal sex especially the receptive ones.
I have not found a site that gives specific odds, but I have not found a site that says most transmission is anally either. In fact, here it says that in much of the world, vaginally is the primary means of transmission:

Yes, it is possible to become infected with HIV through vaginal intercourse. In fact, it is the most common way the virus is transmitted in much of the world. HIV can be found in the blood, semen, pre-seminal fluid, or vaginal fluid of a person infected with the virus. The lining of the vagina can tear and possibly allow HIV to enter the body. Direct absorption of HIV through the mucous membranes that line the vagina also is a possibility.
The male may be at less risk for HIV transmission than the female through vaginal intercourse. However, HIV can enter the body of the male through his urethra (the opening at the tip of the penis) or through small cuts or open sores on the penis.

I looked at the CDC site, the San Fransisco aids site and others, and all say males can get aids from vaginal contact, that the female is at more risk, but most won’t give odds, probably because they are not well established.
The problem is that HIV isn’t that easy to transmit, and even with anal sex with an infected partner it is not certain you will get it. So people start playing mind games with "the odds" but the fact is you are putting yourself at risk, just like Russian roulette.
