Ok, so i'm 17 years old, I've been with my partner for around 2 years now, we're both virgins but have done oral sexual activity for about a year now. none of us have any STD's as we are completely each others first for everything.
I got some tongue ulsers, like lots of small spots on my tongues like when you eat something hot and it burns. then a few nights later i performed oral sex on my girlfriend involving my mouth on her vagina.
she has these ulsers on her tongue and mouth now and believes she has caught them from kissing me but it worried she will now get an STD because i did mouth-vagina action?
