Thanks for the thanks.
I saw your initial comment about the cut on your finger and took it into account.
Thank you so much Dr. Handsfield. I actually did not know this before. You give me a good education. By the way, did you take into consideration that I had an open cut in the corner of finger nail ?
Thank you so much
Welcome to the forum. Thanks for your question.
You, your wife, and anyone else in the house is at absolutely no risk for HIV (or any other STD) from the sexual events and the potential exposures you describe. They call these infections sexually transmitted for a reason: they are transmitted only by sex. If people could get STDs or HIV from such events, they would be far more common than they are, and they would appear from time to time in virgins and others who have not have sex -- but this never happens.
As another example, around the world in the past 30 years, millions of people have lived for years in the homes of people with HIV, sharing bathrooms, kitchens, towels, eating utensils, etc -- and none of these people ever catch HIV (unless they also are sex partners or exposed to large amounts of blood of the infected person).
On top of all that, I would point out that it is very unlikely either your housemate or his sex partner has HIV -- especially if they are not injection drug users or otherwise at special risk.
So no worries, no need for testing, and no need for sexual precautions between you and your wife. All is well.
I hope these comments have been helpful. Best wishes-- HHH, MD
