should I stop having sex?

so today my bf came to my house & he was literally only here for like 40 mins & we did a little "quickie".. then after I was on his phone & he kept asking what I was doing, he wouldn't stop bugging so then he finally snatched it out of my hand. also, after he was getting dressed he was so in a rush to go out w his friends, I asked him to stay for a while longer but he wouldn't so he left.. we go out on dates sometimes but I'm starting to feel like all he wants is sex.. & that he might be hiding something... somebody help idk what to do or say at this point, any advice?
