Should i leave him because the is bad?

after being with my bf 4 about a 2 mths i slept with him for the first time. Truthfully i expected more..i didnt even have an after having an 8 mth drought. I expected so much more. I jus think that this bad experience as changed how i look @ him ually and is affectng our relationship..should i give him a chance to redeem himself or just leave?
