5 weeks ago yesterday, I received unprotected oral sex form a sex worker. I am male, sex worked female. It lasted about 10 mins and I ejaculated in her mouth. Since then, I have been worried sick that I may have caught something from her that I could pass to my wife. I have not had any spots, scabs or rashes, but I do have this constant feeling in my penis. Pain is too strong a a word, but a constant dull ache, especially at the end of my penis and the opening of the penile canal looks a little red. I also feel like I need to urinate all the time, even if very little comes out. I keep going up and down emotionally. One day I feel better as I'm convinced I don't have anything, but other days I worry like hell and this feeling in my penis won't go away. I have had unprotected intercourse and oral sex with my wife since the incident (first time 2 weeks after my experience with the sex worker). Yesterday my wife complained that her vagina was itchy and I noticed her rubbing it a couple of times and of course this has me more worried than ever. We were just at some hot baths and she commented that the itching feeling might be form that. I don't know what to do. I guess I need to go get blood tests for all possible deseases and a urine test for NGU. After 5 weeks without any spots, scabs or rashes, is there anything you can definitely rule out ? Also what tests do you recommend I get done tomorrow, so I can find out once and for all if I have anything. Thanks for your help.
