Bump's under tongue. std/ sti???

[fishinkid]

I am a young teen and have never been sexually active. Yesterday was the first time I ever even kissed a girl. It was my girlfriend, and we made out. Today I noticed that underneath my tongue, at the bottom of the thing that attaches your tongue to the bottom of your mouth, is a little sore, and it may have a bump on it. I'm not sure what it is, is it just a sore, or could it be an std? My girlfriend says she doesnt have anything like that, and I believe her. But i'm to afraid to tell my mom( atleast until I know for sure that it's an std) because she would be soo upset knowing that I even made out with a girl. I have a couple of little clear bumbs on the frenulum in my mouth, the thing that connects my tongue to the base of my mouth. It hurts a little bit, and now the tip of my tongue is a little sore, it may just be raw though. I don't know if it is herpes or what. There isnt blisters or anything. It's been 3 days since I kissed her. Do you think it's an std?

I'm pretty sure it's just a canker sore. It would go away 3-14 days or so. Just keep it clean with a canker sore type of medication. I suggest zilactin-b or anbesol. I highly doubt it's an std. But canker sores are a big pain in the butt, too. At least those go away.

Your descriptions are not consistent with std.Seeing an oral medicine specialist is advised if the lesions persist more than 2 weeks.
