idk if my boyfriend actually likes me for me

so i've been with him for 5 months now, going on six and even though we call everyday, i feel like he just wants nudes from me ? i don't want to think that's true because he seems actually interested in my day sometimes and sometimes i initiate stuff like that too, but it comes up with him almost every time we talk... and when we were in school, he would just find any reason to touch me inappropriately even if i was saying that we shouldn't do that in front of people. also, one time he sat under my desk (it was afterschool in our esports room) and while i was in game someone started saying that he was... for a lack of better words, eating me under the table, and instead of stopping them like i was trying to, he just laughed with them

and even if he isn't with me just for that, i don't think he really wants to know me.. he only asks surface level questions and honestly doesn't really know much about me even after being together for this long, i don't know much about him either but that's because everytime i try to ask a question about him, he always says he doesn't know or just gives a vague answer. i think this is a consequence from only being friends for 2 weeks before starting to date,but i still feel like i should know more about him in 5 months... i've had deeper knowledge about some of my guy friends in less than a semester..

i still love him deeply but i really don't know what to do, because if i ask him if he really likes me, he's obviously gonna be like "yes" but i'll still feel like he's lying.. is this just insecure of me ?
