Suspicious much or overreacting

Idk how to feel about it because I've given him them before and I mean it was just something that happened and he's always kissing on my neck and stuff it's his favorite spot to kiss me but I'm starting to get suspicious and I wanna ask like why can't I give you hickeys you afraid other girls gone see ... But then I'm like idk 💁🏾
