As a regular blood donor, I have always wondered about that question related only to males. How come sodomy with females is never a problem? I admit I am clueless when it comes to medical issues, but with my vast understanding of medicine I would apply the question to sodomy with either sex. I sure wish someone would help my ignorance on this subject.
The FDA and medical field strongly differentiate between the two in terms of risk.
So much so that even women who have had sexually contact with a male who has had sexual contact with other men are deferred from donating blood for a year afterward, I believe.
The key issue likely is how being sexually active with someone is in a medical sense the same as being sexually active with everyone else that person has been sexually active with.
And this:
“Sex with an HIV-positive partner was associated with a 132-fold increase in risk (multivariable adjusted odds ratio) for being HIV-positive, and a history of male-to-male sexual contact was associated with a 62-fold increase in risk.
“By comparison, the increase in risk for a history of multiple sexual partners of the opposite sex in the last year was 2.3-fold.”
“As a group, in the United States, MSM have the highest HIV risk: according to CDC, two-thirds of new HIV infections occur in the approximately 2% of the population who are MSM (Ref. 27). The risk of HIV among MSM is more than twenty-fold higher than that of men who have sex with multiple female partners and women who have sex with multiple male partners (Ref. 32).”

And the questions asked of blood donors:

Note the question asked of women:
“Female donors: Had sexual contact with a male who had sexual
contact with another male in the past 12 months?”
I believe the lovely custom of anal sex is the source of the diseases that they contract and spread.
Homosexual women don’t ordinarily indulge in that particular practice.
To completely answer that question, we would have to delve into the difference between male homosexual behavior, and that of female homosexual behavior.
But to sum it up, male homosexual behavior is far, far, far, far more dangerous and likely to spread disease than is female homosexual behavior.
If you really want the details of the how and why, i'll tell you, but a lot of people would find the conversation off-putting.
