It sounds to me like you need to slow down. Start small. Bring up what it is about a relationship is meaningful, talk about what each of you sees for the future, personal fantasies you have never told anyone etc.
Build your relationship strength and communication. Within that, the topics of concern and desire etc come up.
And dont get married without having already gotten through all of that. Love is not enough to sustain a lifelong commitment. That requires compatibility and good communication skills. Compatibility for LONG RANGE goals, dreams, intentions etc. not just in how to keep house.
