We have a Planned Parenthood office in a nearby town and that is where we went to get tested for syphilis, chlamydia, gonorrhea, and HIV.
They don't provide herpes or hepatitis testing. For those you have to go to a state office which handles testing for those who plan to travel out of the country or...for "other" reasons--I guess that's how they locate all the swinging Iowans.
As far as opening up to your doctor about your sexual lifestyle, that's your call. I imagine it would be a very good idea. But I haven't told mine yet. I've only seen her a few times and don't feel I know her well enough to have that comfort level.
I hope to one day.
If you do suspect you have contracted something you'll need to get tested. Don't put off going to your doctor. You can also go to Planned Parenthood.
