getting fucked is always painful at first.
Some folks simply just can't do it, in some cases is physical pain while in others is psychological and they feel they're being emasculated while doing it.
I may be the minority here, but I would for sure explore my options. Why - to help prevent this from happening to other people, and it may send a message within the area where he lives that this type of behavior will not be tolerated. If it had been rape vs. disease infection would folks say you should still be quiet, and deal with it? How about abuse - deal with that, or report it?
Working for a University and getting yearly trainings on sexual assault, rape, bias, etc. this would actually fall under assault at a minimum where I live. I would also find it morally wrong for someone to intentionally misstate their status on any type of sexually transmitted disease. To not know one is one thing, but to completely lie is another. Yes, it is a very uncomfortable conversation, but that is part of being an adult, and taking responsibility and even more so in the line of work escorts do. I would still expect to know even if it was someone I am just a "buddy" with.
I hope you can get some mental healing, as well as great treatment where you experience very little to no loss in the quality of life. This is always a fear of mine, as well as any other STD/STI (and even though vaccinated, I'm still cautious in regards to COVID). Wishing you the best.
There is more available than just Viagra, Levitra, and Cialis--there is an injection with a very small needle called Tri-mix which might work for you. In any case if you haven't spoken to a urologist about this, you should.
