Welcome back to the forum. Thank you for your continued confience in our services.

You needn’t worry about your penile bruise. Few if any infections of any kind, and no STI, can cause symptoms sooner than ~36 hours and generally it’s 2-3 days and up to a few weeks. Second, no STI starts out as a bruise or other skin discoloration. There is no doubt the bruise is due to minor trauma and not a cause for concern

Female sex workers in brothels, bars, and street walker are generally considered high risk for HIV and other STIs, compared with escorts – i.e. expensive FSWs by appointment. Escorts generally take precautions, are tested frequently, and most of their male clients are low risk as well. That said, in all settings the levels of risk for any particular sex worker are highly variable, That your FSW apparently uses condoms (even for oral sex, which is low risk even if unprotected) is a good sign.

Contact of your skin with saliva or vaginal fluids – penile or anywhere else – isn’t a concern. It virtually always occurs because it is difficult to avoid. But it’s little or no risk for all STIs. That aspect of your exposure shouldn’t concern you.

Should you be tested? That’s a personal as well as medical decision. From a medical/risk perspective for this exposure my judgment is no; the risk is too low. OTOH, risk alone isn’t the only reason for testing:  reassurance itself if a valid reason. If you’re going to be nervous regardless of my evaluation, then before sex with your regular partner wait til 4-5 days after the event and have a urine gonorrhea/chlamydia test; you should have the result in a day or two. You also could consider syphilis and HIV blood tests after 6 weeks, but the risks are so low that I would not advise holding off that long on sex with Ms. Regular.

I hope these comments are helpful. Let me know if anything isn’t clear.
