Boring sex

So whenever I have sex with my boyfriend (been together 8 months, lost virginity in January) I get extremely bored and only think about masturbating later because he doesn’t please me good enough, like I don’t even get almost to a climax, but I don’t wanna tell him and hurt his feelings (he’s soft and gets in his chest easily) 🤦🏽‍♀️ idk what to do..Is this bad ?
