I was with another man who said he was HIV negative. While we were grinding, I noticed that I had entered him (unprotected). This was not for more than 10 seconds. While he said he was negative, I have no way of making sure of that and I am terrified that because of a few second slip I might now be infected. This was about a week ago, so it is too early for me to get tested. Am I at a high risk or likelihood for infection because of this incident? Any guidance here would be greatly appreciated.
Many thanks.
