not feeling anything???

My boyfriend and I lost our virginity to each other about 4 months ago. Since we both are still high schoolers, we live with our parents and have had trouble finding a convenient time and place to have sex. And when we do, neither of us tend to feel much. We always tend to skip out on foreplay, which is possibly one issue, and he may have desensitized himself from jacking off. We are trying to fix it, cause we're hopelessly in love and very comfortable with one another. Any ideas on what the cause is or how to fix it?
