Guys, Why does my boyfriend always have to touch my body so much (groping)?

My boyfriend always loves To touch my boobs and suck them as well as grabbing my ass or my yk but sometimes he does it too often like for example I was out with him and his mum and dad in public and he grabbed my ass and then later on my boobs I don't know how to confront him about this although most times I really don't mind but also just wondering can some guys tell me why he is doing this (by the way when I tell him I am uncomfy he stops).
