Hi, 
I assure you this is my last post on the forum for awhile, as I am certainly not trying to take advantage of the educational value and knowledge of the site.  This situation just presented itself a few hours ago and it worried me enough to purchase another question.

I was out to dinner with a friend and he took a sip of my soda using my straw. I immediately turned the straw upside down, put it back in my soda, and drank from the opposite side for the remainder of the drink. I have never been worried about sharing drinks before, however with my recent HSV research and inquisitions regarding my previous situation, I am hypersensitive at the moment. I did not see a cold sore on his lips, but I asked if he ever got a cold sore and he replied, "I don't think so." He knew cold sores are a form of herpes, but he asked questions about what cold sores look like, if they are strictly outside the mouth etc. (I believe he has experienced some kind of sores IN the mouth before-he has had two sex partners: one was a virgiAfter explaining more about them, he said he has never had one. Of course, I know people who have never experienced cold sores can mistake them for other things. I am also aware that some people have cold sores  caused by HSV2. If he has, in fact, had cold sores before and his are caused by HSV2, what are the chances of acquiring oral HSV2 from him sipping from my straw and me drinking from it?  I peeled a layer of chapped skin from my bottom lip shortly before dinner, so I had exposed skin at the time. I am worried about the possibility of acquiring new infection, as shedding occurs from saliva asymptomaticly. 

I apologize for asking such a ludicrous question on the forum, as I am sure I am very far fetched here, I just really need some peace of mind before I kiss/have oral sex with my boyfriend.  I am trying very hard to use logic and scientific information to calm my fears- but I find you are the most reliable source I have and trust for accuracy. Thank you.

The chances are zero.
You may finish your last two questions on this subscription, but then we need to stop.  OK?

Yes, I agree. It stops after this subscription. I am just grateful for your replies at all, thank you.

1- I am glad to hear you say there is zero risk. I know I turned the straw upside down, but I also know my skin was exposed and I drank from the side of the cup as well so I'm not 100% confident my lips did not touch the glass or straw where his lips were. I know the mouth is susceptible through mucous membranes.  Would you mind explaining to me why the encounter I described is zero risk so that I can use these facts and logic to stop illogical, worrisome thoughts?

2- I have read a lot of conflicting things online: some say you can get oral hsv2 from sharing utensils, cups, and straws. Others say it must be skin-to-skin contact such as kissing. What is the truth about oral hsv2 transmission? Since I already have  oral HSV1 is it difficult to acquire HSV2 orally as well?

3- So let's say this friend did have an active cold sore caused by HSV2 at the time that I didn't see and he took a sip from my straw and I drank immediately from the same straw right afterwards. What would be the chances of getting HSV2 this way? (Just in case in the future I accidentally share with someone who has the infection and doesn't know) 

4- My last test results came back negative HSV2, approximately 6 weeks after I began having mostly protected sex with my bf.  In fact, all three of my previous HSV2 test results came back negative. The last time I had unprotected sex was 5 days prior to my HSV2 blood  test, so I know even if I was infected, antibodies probably wouldn't show up. My question is, since I've been on valtrex for over a month, would that affect my results? 

Thank you!

Oh and I should mention that I chew the inside of my lips and cheek a lot so I am sure there are many micro abrasions and cuts in my mouth, which is also why I worry about infection having access into my system.

1.  The encounter is zero risk because even if there was virus on his end of the straw (which is unlikely), the virus would then be in the liquid and the dilution factor would keep you from being infected.  Plus I doubt there could possibly be enough virus on a straw to infect anyone even if they came into direct contact with the straw.

2  HSV 2 requires skin to skin contact - there are no documented cases of anyone getting HSV 1 or 2 by sharing utensils

3.  see answer to the first question

4.  Valtrex can impact test results yes.  but if your boyfriend is negative, it doesn't matter.

Jennifer, you need help with this issue.  You are asking about really out there situations and this is a sign you are in trouble with herpes thoughts.  We are not going to answer any more of your questions because this only feeds the obsession.  I say that with affection and concern for you
