Sounds like culture testing. I'm not sure
what they'd do but it sounds like they're
planning to do more than your last gyno
did, so that's good.
Sex for some women needs to have the
emotional attachment and not just the
physical one. This is all just my opinion
now, but I feel you should wait until you
find someone you truly like, even love,
before having sex again. By then maybe,
you'll have gotten an answer from a
doctor.
