I had a recent experience in Pattaya, Thailand that concerns me. My first day there, about a week ago, I was out drinking and ended up having unprotected oral sex performed on me by a local bar girl. I never ejaculated from the oral sex, but I did masturbate until finished. My last night there I went out again and picked up another bar girl, whom I had unprotected oral sex with and protected sexual intercourse. From what I remember, I placed the condom on properly, and the sex did not last long because I could not finish. We then resumed unprotected oral sex for a bit and she placed her finger in my anus. My anus is still a little sore about a day and a half later, but I did not see any cuts anywhere that I could remember. I never did ejaculate during the whole experience, but I am worried about possible STDs. I have no symptoms to speak of so far from either experience, but how long should I wait/when should I get checked out? I spoke with my public health clinic, and they take walk-ins for people who have no symptoms. I just want to rest a little easier and find out when I should be checked out as I have heard some bad things can be picked up there.
