Is it normal that my gums swell up??

It means they are inflamed. You also might have deep pockets. Flossing should help and might try a better brand of toothpaste. This happens sometimes.

My boyfriend is allergic to all fruit and I am allergic to nuts and gluten and cinnamon gum burns ulcers inside my mouth.

Take notice of what you have eaten when it happens, you could be allergic to something if it only happens at certain times.

Do they swell up after you suck a lot of cocks?

Thanks guys
