My girlfriend just started complaining about her vagina being sore ,swollen and really itchy and there's a little bit of on odd smell to it, and its red.I need to know what's wrong, i've had unprotected sex with her since this and nothing seems to be happing to me so i'm not sure what it is.There are only two things i think it can be an STD or a rash that she got from the place we have sex normally cause i got a rash that was sore ,red ,swollen and had red bumps all over my stomach and arms from cleaning in the area and she wiped her vagina with a cloth that was on the floor in the same area where i got my rash so please tell what you think thank you
