Hello, I recently engaged in unprotected oral sex with a man and, although he assured me he tested negative for stds a few months ago, I wanted to know how much fluid exposure it takes to be considered at high risk of contracting an std. The amount of oral I performed was very mild and there was no ejaculation in my mouth. Someone on the panel already responded to my question, but I would like a second opinion. Is a small amount of precum enough to put me at a high risk of contracting an std? Thank you!
