Guys & Neck Kissing

Malia
So my first guy I had sex with did not like me kissing his neck, I'm no longer with him and been with other guys inbetween him, but I've restrained from kissing their necks. Now I'm with a new guy who I really like and I'm wondering if I should kiss his neck or if it will bother him like the first guy I had sex with. Anyone have guidance or opinions on the topic?
