Okay, well not too long ago, me and my partner just had sex..now my vagina is swollen, and it kind of hurts not really..is that a bad thing?

See a gynecologist: what matters most is the time course of your symptoms. If this is something that just happened in the last few hours, it is unlikely to be a yeast infection or a bacterial infection. More likely this could be an allergic reaction. Regardless you should talk to your gynecologist about your issue and get a pelvic exam to make sure that there isn't anything else going on.
