OP,.sorry to hear this and like Mirror I'm glad it's being talked about. I try to be really mindful of cross contamination but one thing that always feels awkward is fiddling about with the condom after touching his cock. I always try to sneakily wipe my fingers on some antiseptic wipes while hoping that some smouldering eye contact will distract him from the 'clinical ' side of things. I guess we shouldn't be ashamed of doing everything we can to stay healthy.
Get a pump dispenser of alcohol based hand sanitiser.
It takes literally 5 seconds to do both hands and can be easily camoflaged by looking in drawers/bags for condoms.
You will need to use skin lotion after each booking though as it really dries your skin. If I run out of lotion my hands look like fucking cheese graters.
I've had oral chlamydia and it's really not a big deal. It's a shot of antibiotics (and it was more time consuming for me because I have an allergy to penicillin) and then you go back and get tested in a week and it should be all clear. I would imagine its similar with genital chlamydia.
Back in the early 90s I caught HPV aka genital warts from an unprotected one night stand. At the time the only treatment I was offered was basically acid (salycylic?) to burn the warts off, and a yearly cervical smear instead of 3 yearly.
Last time I had a smear I told her this info and the nurse said it was a total waste of time having annual smears as the vast majority of HPV strains don't lead to cancer and they no longer recommend this for females presenting with genital warts.
