So I went to Amsterdam and over 3 nights got with 3 transexual workers ( all just off the main red light not street walkers or off the internet) all the anal sex was protected although I had unprotected oral sex and rimmed all 3 although there was no cum possibly a tiny bit of precum to the best of my knowledge ( was pretty high) all were symptom free and I didnt have any sores on my mouth jus dry lips possibly nearing the verge of being chapped because of smoking lots.. Wondering what my chances of an std as I'm seriously worried
