Hello, doctor.
I am a gay man. I have been in a monogamous relationship with my partner for four years. Because we were both tested for common STDs and HIV, we agreed that we would make our relationship exclusive so that we could have sex without condoms.
About four weeks ago, I was dragged to a club with a few friends of mine and drank quite a bit more than I really intended. I will not bore you with further exposition: I ended up giving oral sex to another male whose status was unknown to me. When he ejaculated, I swallowed some of his semen and the rest went onto my face and over my eyes. Some of the semen got into my eyes and made them sting.
A couple of weeks after the event, I developed a sore throat that's come and gone for the last two weeks. My temperature seems to have been elevated occasionally, usually 99.2 or 99.3, but I've never seen it break 100F, so maybe this is normal. At one point I had muscle ache exclusively in my gluteal muscles, but I thought that maybe this was due to poor posture affecting circulation. That particular muscle ache only lasted a day or so and then went away. I've had an ulcer in my mouth in the last few days that may have been due to stress from this event and from an interview I had recently. The nodes in my neck feel a little enlarged and tender, but I don't think I can judge with much accuracy since I have allergies.
I intend to get tested at six weeks. The clinic here in Dallas does a free test that includes a third generation ELISA, a PCR, and a syphilis test. In the meantime, I have been avoiding anal sex with my partner so that he is not put at any risk whatsoever.
My question is: is it safe to continue having sex with him before the test? I can tell him about this event if I must. I am certain that he will both understand and forgive me. Yet the revelation would cause him great pain, and I would prefer to simply erase this accident and move on.
I greatly appreciate your advice and consideration.
