On Thursday, I received unprotected oral sex from a "happy ending masseuse," which lasted less than a minute, with bo ejaculation. This is the first time I have done such a thing, and I was frankly surprised that she began the oral. (I assumed the "service" would end in a hand job.)
Sunday, while playing softball, I slid into a base, and got a pretty intense abrasion on my knee & shin - it's about 5 inches long, and about three inches across. Scraped up pretty bad, scabbing, weeping, lost a lot of skin.
On Monday, I have a mild swelling in what I believe is my lymph node on the same side as the leg injury. I also have some muscle strain in the area due to the vigorous running in the same softball game.
I've seen in the forums that oral sex is an inefficient way to transmit STDs. So my question is this - would a swollen lymph node show up as a symptom of STD in only four days, or would it take longer? Or is it more likely that the lymph node is a reaction to the injury (and/or possible infection) on my leg?
Advice/thoughts? Thanks.
