I kissed a guy (french kissing) with tongue, then after few hours i realized i have a small mouth ulcer inside upper lip that is few days already and not painful anymore and small already. not totally healed but not painful to the point i forgot i have a mouth ulcer. it is not bleeding. i also have a dry cracked portion on the corner of my mouth. it cracks when i open my mouth wide but it's not bleeding. but it's not healed yet. my question is can i get hiv from the french kissing because i am worried that whatever in his mouth (not sure if he has blood or what because who inspects inside partner's mouth before kissing) infected me thru my mouth ulcer and cracked corner of lip. we never engaged in anal or oral or masturbation
