If your immune system is weakened, you've probably learned a lot about infection control already, think with your head not your dick.
Choose your lady carefully and if you see signs of poor hygiene get out of there. Most of the escorts that I have visited are very clean and careful, and probably safer to visit than the average doctors or hospital waiting room. Bring your own towel and toiletries for added safety. Avoid owo and fk, keep everything covered and risk is minimal.
My wife caught me wearing ladies underwear and threatened to leave me.
So I packed up all her clothes
And left.
