Frottage and mutual masturbation are not penetrative sexual activites. There are no cases of HIV even suggested to have been transmitted through these activities. EWH
Out of curiosity how is it that mutual masturbation even with fluids and frottage are considered no risk, but oral sex is considered low risk? I would think that contact with fluids in such a way during frottage and mutual masturbation would pose to be more of a risk than oral sex?
As I said, your tests prove you did not get HIV from the exposure you have described. There is no reason related to that encounter to abstain from sex. EWH
I just want to make sure its ok to resume having sex with my husband without worrying about being infected and HIV testing not being able to pick it up.
Welcome to our Forum. It is my pleasure to tell you that you now have three definitive test results which show that you did not get HIV from the exposure that you reference. While the "official” recommendation for provision of completely reliable tests is at 3 months (12 weeks), studies show that HIV tests, including both the UniGold blood tests and the OraSure tests provide completely reliable results at any time more than 8 weeks. Thus your tests are reliable. Brushing your test before testing should not alter the reliability of the OraSure test. On the other hand, I have no experience with how wiping out the inside of your mouth with an anti-bacterial wipe would influence the test but doubt that it would be a problem (why did you do this?- I suspect it tasted horrible.)
In answer to your other questions:
1. If he was positive, could being fingered by a guy using his bodily fluid transmit HIV? Also, if he rubbed the outside of my vagina with his penis head with his fluid on it?
No, HIV is not transmitted by masturbation, nor rubbing the outside of your vagina with his penis, as long as there is no penetration.
2. If my tests were "3rd generation" is 3 months conclusive?
See above, your test results are conclusive.
3. Do I need anymore testing? I am suffering great anxiety due to this exposure 8 months ago.
There is no need for further testing related to your exposure 8 months ago. time to move forward without further worry.
I hope these comments are helpful. EWH
