I wish someone would write about P.I.D not caused by stds. I've had P.I.D. twice, not caused by STDS or STI's. I am monogonous. Am not sexually promiscuous. have only had intercourse with 2 people. Once with my ex years ago, whom i lost my virginity to, and now with my bf of 2 1/2 years. It's great and all that people write about how P.I.D is most commonly caused by STDs..but what about the few of us that have had it a couple times that aren't caused by STDs. I'd like more info on that.
