Kissing is not a risk for HPV. Its a risk for HSV1, but so many people have that already that you'd just have to avoid kissing to avoid HSV1. HSV2 is very rarely an oral infection.
CMV can be spread by kissing, but its not considered an std.

Very little risk..almost none. Bumps of the tongue are more commonly cysts and are perfectly benign.
By kissing, CMV(no symptoms), some HPVs, and HSV-1/2 can be trasmitted.
upi can't get anything from kissing. i suggest a theapist to help deal with this anxiety you have.
