Why does your stomach hurt really bad when you find out a guy is attracted to you?
Either you don't like him and you feel like you want to throw up or its "the butterflies" when you like him back.
thats just you.
Because you get super nervous/excited/anxious. Used to happen to me every Christmas until I got older and opening presents wasn't my favorite part anymore
You maybe don't like him that has happen to me when Someone creepy like me
