My bf (m28) and I (f28) have a closed relationship but sometimes we allow an extra when the opportunity comes up. We've only had the privelage a couple times now and just recently had a woman we've known for a good while become interested in being an extra, so we obliged.
This encounter has happened twice within a couple weeks, there was penetration and no rubber (very dumb, I know), but after both times were said and done, I was having casual conversation with her when she mentioned that her ex gave her chlamydia 6 years ago. She happened into getting tested and found out her bf at the time was cheating on her because she tested positive for it then. She said she's been tested every sexual encounter since because she didnt want it to happen again and didn't mention having it again but I am fearing the worst because from what I understand about this particular STI is that it doesnt actually go away.
Should I be worried about this or has it been so long that it being active enough to spread is unlikely?
