My bf or me?

So like idk if all guys are like this. (He’s my second bf and first one I had sex with). Like my bf is 22. I’ll be 21 in 6 days 🙌🏻 He wants sex when we wake up, sometimes in the middle of the day when he’s horny and at night before we go to bed. Like I get it, I’m on my period this week but he literally told me this morning he’s gonna ‘fap’ before ‘this class’ and ‘this class’. I get uncomfortable when he jerks off in front of me. He pulls out porn on his phone when I don’t want to do it. He’ll say he has to poop and leave for like a half hour on the toilet. One time he told me he faps. We’re in college and school work is important to me. I’d rather get work done than waste time having sex because I don’t really enjoy it. I don’t know if I don’t like sex or I don’t like him but every time he asks I’m like: “ugh omg 🙄” and he’s like “way to be enthusiastic”. like sex isn’t a necessity for me. I find it weird because Ik some girls want it all the time. I hardly get horny. If I see a hot guy, I don’t automatically picture me having sex with him, it’s more of having a loving relationship with him. My bf has long nights Monday and Tuesday because he has labs due. He said he going to get sleep last night but he ends up going to bed at 2:30 because he was playing Xbox. He doesn’t follow through with what he says and that pisses me off because I follow through with the things I say. I eat healthy and track my calories on myfitnesspal. He’s always telling me to get off my phone and sometimes he’ll knock it out of my hand while I log my calories. He does it to be funny but I get mad. I try and motivate him to eat better because he wants to lose weight. He then eats crappy food and then says he has to make better decisions but still eats bad food. He doesn’t listen to me. He says to stop nagging. Like I’m I being too pushy? He wants to order Chinese food like all the time. Like am I just more mature than him? Do real men that follow through with things really exist? Do they understand we don’t want sex 25/8?!?!? (lol) hELP!!!
