Also Doctor, If you believe that 10 seconds are not enough for the virus to become non-infectious on a toilet seat, it doesn't apply to the 6o seconds. Meaning, it can still be infectious at 10 seconds, but can't still be infectious at 60 seconds, correct? 

Welcome to the Forum and thanks for your confidence in our service.  I'll be glad to comment.  The sort of exposure that you describe is a no risk event, far more analogous to mutual masturbation in which both partners get each others genital secretions on one another than penetrative sexual exposure.  As you already know (thanks for looking at replies to other clients) HIV very quickly becomes non-infectious upon exposure to the environment- both the drying effect or being outside the body, as well as the lower temperature contribute to this rapid loss of infectivity.  I am not familiar with the situation from which you quote Dr. Handsfield but again, when genital secretions are outside the body, they are considered non-infectious for HIV and should not raise concerns about acquisition of infection.    I would not worry about this exposure and would certainly not recommend PEP for an exposure such as this.  EWH

And doctor, let me note that the semen was room temperature on a toilet seat, to which I  exposed myself after 60 seconds have passed since the other guy ejaculated. 

I was going to reply when your follow-up question(s) arrived but held off as you seem to ask several questions serially.  As I suspect you know, following this response, you will have one more follow-up question which will be replied to before the thread is closed. 

With respect to 10 , 20, 30 or 60 seconds or more, I think you are splitting hairs in a way which is scientifically irrelevant.  Here are the facts, there are NO proven instances in which a persons has acquired HIV from a toilet seat or inanimate surface of this sort. Similarly, there are not even any instances in which a person has been proven to have been infected with HIV during mutual masturbation during which it is COMMON for persons to ejaculate on one another and thus IMMEDIATELY get each others' genital secretions of each other during vigorous sexual contact.  NONE!

As I already said, I do not know the statement that Dr. Handsfield made which you are quoting however, there is an important nuance as well.  HIV does become non-infectious before it is dead.  When the virus is exposed to the environment, it becomes non-infectious (FACT!) and NO ONE has ever been infected through the sort of environmental exposure you have described.  The events you describe did not put you at risk for HIV (even in the unlikely event that the genital secretions your penis apparently "vigorously" came into contact with possible genital secretions on a toilet seat. 

I hope this explanation is helpful.  I cannot imagine how the scenario of indirect exposure you describe would put you at any risk for HIV and as I said early, would certainly not suggest PEP for you in the situation you describe.  EWH

Please doctor, please, just tell me if I can be certain 100% that 60 seconds are enough for a hiv to become non-infectious on toilet seat? And please doctor, please, tell me if 60 seconds (can not survive) is not the same as 10 seconds (which can survive here). Please doctor address the question of whether 60 seconds is enough while 10 seconds is not enough. NOTE: I will be okay with 10 seconds not enough, because more time has passed (just tell me if this is true), but I need to know about the 60 seconds. many thanks doctor!!

Sigh

Final answers to these repetitive questions:

1. Yes, it is long enough for ejaculate to be non-infectious (in effect, I already said this above)

2. Again, previously answered. There is no reason to think that you could get infected with HIV through contact with a toilet seat 10 seconds after another, HIV infected person has ejaculated on that toilet seat. (The answer to this should have been obviously from the earlier answers.

There will be no further replies. EWH

Doctor please answer question number two about whether the statement is true or not. IT COULD SAVE MY LIFE please doctor.

Please doctor, I beg you, just tell me if this is true: (10 seconds could be not enough for the virus to become non-infectious, but 60 seconds are 100% enough for the virus to become non-infectious on toilet seat. 

Doctor please, I beg you, answer the above question. PLEASE.
