Your feelings are just as valid as your partner's. If you're not ready, you're not ready. If he can't accept that I'd seriously consider ending the relationship.
However, why not try simply explaining things to him the way you did to us? It sounds like you really do care about him but simply aren't ready for sex right now and there's nothing wrong with that.
