If you're not sure, the best thing is to see your doctor, so he/she can confirm (or rule out) a yeast infection. Most times, once you've gotten a confirmed diagnosis, you can identify any yeast infection that occurs in the future. It also goes without saying too that anyone who is sexually active should have annual STD testing, so if you haven't done that within the last year, now would be a good time to do so.
Also, you need to lay off the feminine hygiene products. There should never be a need to douche unless it's something your doctor recommends. Douching and then using all of those other products destroys the normal flora in the vagina tract which are actually there for very good reasons. Destroying those normal GOOD bacteria will actually make you much more susceptible to things like yeast infections.
Good luck!
Yep yeast infections pass back and forth. Both need treatment
Yes go to the DR..If you have it, or he has it, you both need to be treated if it is any type of infection..If not you both will continue to pass it back and fourth.
