Yea I have known him for 4 months and we always discussed STDs, but sometimes people can hide things. Lol. I am thinking that its wisdom tooth
Because it is your BF not a stranger. Hoping you know him, trust him, and know his sexual history. Also, because there was no body fluid involved and because it was brief. All this points to doubting it is an STD.
I once gave oral sex to a woman who said she had herpes (after the fact). That was years ago. I never got it.
How come you doubt its an STD??
Dentist or doctor, your choice. I doubt it is an STD.
